Pull HID updates from Jiri Kosina:

 - improvement in the way hid-bpf coexists with specific drivers (others
   than hid-generic) that are already bound to devices (Benjamin
   Tissoires)

 - removal of three way-too-aggressive BUG_ON()s from HID drivers (He
   Lugang)

 - assorted cleanups and small code fixes to HID core (Dmitry Torokhov,
   Yan Zhen, Nathan Chancellor, Andy Shevchenko)

 - support for Corsair Void headset family (Stuart Hayhurst)

 - Support for Goodix GT7986U SPI (Charles Wang)

 - initial vendor-specific driver for Kysona, currently adding support
   for Kysona M600 (Lode Willems)

 - other assorted code cleanups and small bugfixes all over the place

+description: |
+  Supports the Goodix GT7986U touchscreen.
+  This touch controller reports data packaged according to the HID protocol
+  over the SPI bus, but it is incompatible with Microsoft's HID-over-SPI protocol.
+
+  NOTE: these bindings are distinct from the bindings used with the
+  GT7986U when the chip is running I2C firmware. This is because there's
+  not a single device that talks over both I2C and SPI but rather
+  distinct touchscreens that happen to be built with the same ASIC but
+  that are distinct products running distinct firmware.
