Merge tag 'hid-for-linus-2025082901' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid

Pull HID fixes from Jiri Kosina:

 - fixes for memory corruption in intel-thc-hid, hid-multitouch,
   hid-mcp2221 and hid-asus (Aaron Ma, Qasim Ijaz, Arnaud Lecomte)

 - power management/resume fix for intel-ish-hid (Zhang Lixu)

 - driver reinitialization fix for intel-thc-hid (Even Xu)

 - ensure that battery level status is reported as soon as possible,
   which is required at least for some Android use-cases (José Expósito)

 - quite a few new device ID additions and device-specific quirks
