Nikhil Chatterjee 857e71cb0a HID: bpf: Add Huion Inspiroy Frego M button quirk ...

The Huion Inspiroy Frego M pen report descriptor exposes the second
side button as Secondary Tip Switch instead of Secondary Barrel Switch.
This makes userspace see the control as the wrong pen button.

Add a HID-BPF report descriptor fixup for the Bluetooth 256c:8251
device and USB 256c:2012 L610 variant. The fixup matches the expected
pen descriptor and rewrites the offending usage from Secondary Tip
Switch to Secondary Barrel Switch.

Tested by building the HID-BPF object with:

  make -C drivers/hid/bpf/progs Huion__Inspiroy-Frego-M.bpf.o
