Ben Horgan c2803bd580 arm_mpam: Stop using uninitialized variables in __ris_msmon_read() ... Dan has reported two uses of uninitialized variables in __ris_msmon_read(). If an unknown monitor type is encountered then the local variable, now, is used uninitialized. Fix this by returning early on error. If a non-mbwu monitor is being read then the local variable, overflow, is not initialized but still read. Initialize it to false as overflow is not relevant for csu monitors. Fixes: 823e7c3712 ("arm_mpam: Add mpam_msmon_read() to read monitor value") Fixes: 9e5afb7c32 ("arm_mpam: Use long MBWU counters if supported") Reported-by: kernel test robot <lkp@intel.com> Reported-by: Dan Carpenter <dan.carpenter@linaro.org> Closes: https://lore.kernel.org/r/202512091519.RBwiJcSq-lkp@intel.com/ Closes: https://lore.kernel.org/r/202512100547.N7QPYgfb-lkp@intel.com/ Signed-off-by: Ben Horgan <ben.horgan@arm.com> Reviewed-by: Jonathan Cameron <jonathan.cameron@huawei.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>		2026-01-08 19:03:15 +00:00
