Jim Cromie 0b8f96be9b dyndbg: fix pr_err with empty string
this pr_err attempts to print the string after the OP, but the string
has been parsed and chopped up, so looks empty.

Jim Cromie f678ce8cc3 dyndbg: fix a BUG_ON in ddebug_describe_flags
ddebug_describe_flags() currently fills a caller provided string buffer,
after testing its size (also passed) in a BUG_ON.  Fix this by
replacing them with a known-big-enough string buffer wrapped in a
struct, and passing that instead.

Also simplify ddebug_describe_flags() flags parameter from a struct to
a member in that struct, and hoist the member deref up to the caller.
This makes the function reusable (soon) where flags are unpacked.

Jim Cromie 81d0c2c609 dyndbg: fix overcounting of ram used by dyndbg
during dyndbg init, verbose logging prints its ram overhead.  It
counted strlens of struct _ddebug's 4 string members, in all callsite
entries, which would be approximately correct if each had been
mallocd.  But they are pointers into shared .rodata; for example, all
10 kobject callsites have identical filename, module values.

Its best not to count that memory at all, since we cannot know they
were linked in because of CONFIG_DYNAMIC_DEBUG=y, and we want to
report a number that reflects what ram is saved by deconfiguring it.

Also fix wording and size under-reporting of the __dyndbg section.

Heres my overhead, on a virtme-run VM on a fedora-31 laptop:

  dynamic_debug:dynamic_debug_init: 260 modules, 2479 entries \
    and 10400 bytes in ddebug tables, 138824 bytes in __dyndbg section

Jim Cromie 481c0e33f1 dyndbg: refine debug verbosity; 1 is basic, 2 more chatty
The verbose/debug logging done for `cat $MNT/dynamic_debug/control` is
voluminous (2 per control file entry + 2 per PAGE).  Moreover, it just
prints pointer and sequence, which is not useful to a dyndbg user.
So just drop them.

Also require verbose>=2 for several other debug printks that are a bit
too chatty for typical needs;

ddebug_change() prints changes, once per modified callsite.  Since
queries like "+p" will enable ~2300 callsites in a typical laptop, a
user probably doesn't need to see them often.  ddebug_exec_queries()
still summarizes with verbose=1.

ddebug_(add|remove)_module() also print 1 line per action on a module,
not needed by typical modprobe user.

This leaves verbose=1 better focussed on the >control parsing process.

commit 4bad78c550 ("lib/dynamic_debug.c: use seq_open_private() instead of seq_open()")'

The commit was one of a tree-wide set which replaced open-coded
boilerplate with a single tail-call.  It therefore obsoleted the

Jim Cromie e20e310c81 dyndbg-docs: eschew file /full/path query in docs
Regarding:
commit 2b6783191d ("dynamic_debug: add trim_prefix() to provide source-root relative paths")
commit a73619a845 ("kbuild: use -fmacro-prefix-map to make __FILE__ a relative path")

2nd commit broke dynamic-debug's "file $fullpath" query form, but
nobody noticed because 1st commit had trimmed prefixes from
control-file output, so the click-copy-pasting of fullpaths into new
queries had ceased; that query form became unused.

Removing the function is cleanest, but it could be useful in
old-compiler corner cases, where __FILE__ still has /full/path,
and it safely does nothing otherwize.

So instead, quietly deprecate "file /full/path" query form, by
removing all /full/paths examples in the docs.  I skipped adding a
back-compat note.

Ashok Raj 3f9a7a13fe PCI/ATS: Add pci_pri_supported() to check device or associated PF
For SR-IOV, the PF PRI is shared between the PF and any associated VFs, and
the PRI Capability is allowed for PFs but not for VFs.  Searching for the
PRI Capability on a VF always fails, even if its associated PF supports
PRI.

Add pci_pri_supported() to check whether device or its associated PF
supports PRI.

Marius Zachmann fa4dac3e1b hwmon: (corsair-cpro) add reading pwm values
This adds the possibility for reading pwm values.
These can not be read if the device is controlled via
fan_target or a fan curve and will return an error in
this case. Since an error is expected, this adds some
rudimentary error handling.

Changes:
- add CTL_GET_FAN_PWM and use it via get_data
- pwm returns -ENODATA if the device returns error 0x12
- fan_target now returns -ENODATA when the driver is
  started or a pwm value is set.
- add ccp_get_errno to determine errno from device error.
- get_data now has a parameter to determine whether
  to read one or two bytes of data.
- update documentation
- fix missing surname in MAINTAINERS

Marius Zachmann 40c3a44542 hwmon: add Corsair Commander Pro driver
This is v7 of a driver for the Corsair Commander Pro.
It provides sysfs attributes for:
- Reading fan speed
- Reading temp sensors
- Reading voltage values
- Writing pwm and reading last written pwm
- Reading fan and temp connection status

It is an usb driver, so it needs to be ignored by usbhid.
The Corsair Commander Pro is a fan controller and provides
no means for user interaction.
The two device numbers are there, because there is a slightly
different version of the same device. (Only difference
seem to be in some presets.)

Squashed:
 hwmon: (corsair-cpro) add fan_target

 This adds fan_target entries to the corsair-cpro driver.
 Reading the attribute from the device does not seem possible, so
 it returns the last set value (same as pwm).

 send_usb_cmd now has one more argument, which is needed for the
 fan_target command.

Alexander A. Klimov e263f2d3c2 hwmon: (tmmp513) Replace HTTP links with HTTPS links
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
          If both the HTTP and HTTPS versions
          return 200 OK and serve the same content:
            Replace HTTP with HTTPS.

Josh Lehan 8ba75b2028 hwmon: (pmbus/core) Use s64 instead of long for calculations
Using s64 type, instead of long type, for internal calculations and for
the sysfs interface.

This allows 64-bit values to appear correctly on 32-bit kernels.
As wattage is reported in microwatts, monitoring a power supply over
2KW requires this.

Although it may seem unlikely to run a 32-bit kernel on such a large
machine, enterprise servers often include a BMC, and the BMC might be
running a 32-bit kernel.

Arvind Sankar 587af649bc x86/build: Move max-page-size option to LDFLAGS_vmlinux
This option is only required for vmlinux on 64-bit, to enforce 2MiB
alignment, so set it in LDFLAGS_vmlinux instead of KBUILD_LDFLAGS. Also
drop the ld-option check: this option was added in binutils-2.18 and all
the other places that use it already don't have the check.

This reduces the size of the intermediate ELF files
arch/x86/boot/setup.elf and arch/x86/realmode/rm/realmode.elf by about
2MiB each. The binary versions are unchanged.

Move the LDFLAGS settings to all be together and just after CFLAGS
settings are done.

regulator: fix memory leak on error path of regulator_register()
The change corrects registration and deregistration on error path
of a regulator, the problem was manifested by a reported memory

        ...

The memory leak problem was introduced as a side ef another fix in
regulator_register() error path, I believe that the proper fix is
to decouple device_register() function into its two compounds and
initialize a struct device before assigning any values to its fields
and then using it before actual registration of a device happens.

This lets to call put_device() safely after initialization, and, since
now a release callback is called, kfree(rdev->constraints) shall be
removed to exclude a double free condition.

Merge series "ASoC: qcom: Use qcom_snd_parse_of() for apq8016_sbc" from Stephan Gerhold <stephan@gerhold.net>:
At the moment we have two separate functions to parse the sound card
properties from the device tree: qcom_snd_parse_of() for DPCM and
apq8016_sbc_parse_of() without DPCM. These functions are almost identical
except for a few minor differences.

This patch set extends qcom_snd_parse_of() to handle links without DPCM,
so that we can use one common function for all (qcom) machine drivers.

Stephan Gerhold (7):
  ASoC: qcom: Use devm for resource management
  ASoC: qcom: common: Use snd_soc_dai_link_set_capabilities()
  ASoC: q6afe: Remove unused q6afe_is_rx_port() function
  ASoC: qcom: common: Support parsing links without DPCM
  ASoC: qcom: common: Parse properties with "qcom," prefix
  ASoC: qcom: apq8016_sbc: Use qcom_snd_parse_of()
  ASoC: qcom: common: Avoid printing errors for -EPROBE_DEFER

ASoC: soc-component: don't report of_xlate_dai_name failures
With commit e2329eeba4 ("ASoC: soc-component: add soc_component_err()")
every error different for ENOTSUPP or EPROBE_DEFER will log an error.

However, as explained in snd_soc_get_dai_name(), this callback may error
to indicate that the DAI is not matched by the component tested. If the
device provides other components, those may still match. Logging an error
in this case is misleading.

Don't use soc_component_ret() in snd_soc_component_of_xlate_dai_name()
to avoid spamming the log.
