Hi, Thanks for your contribution but there are many things wrong with your patch submission: - you used html which should be rejected by the mailing list - your mail client completely messed up the format and the patch is not applicable in its current state. - your signed-off-by is not correct as it's missing your email. Please make sure to use `git send-email` or `b4` for your future submissions Also, the patch in itself (or what I could guess on the email I received) is wrong. You should not tamper with hid-core for that but need a dedicated report descriptor fixup in the target driver. However, the device seems to rely on hid-multitouch which I'd rather not have report descriptor fixups in there. Maybe the simplest solution is to rely on HID-BPF and submit a new driver fix to https://gitlab.freedesktop.org/libevdev/udev-hid-bpf or if you want to directly submit said fix to the kernel in the directory drivers/hid/bpf/progs.
