HID: asus: Add event handler to catch unmapped Asus Vendor UsagePage codes (e98e3809) · Commits · 戴 / test

Various Asus devices generate HID events using the Asus Vendor specific UsagePage 0xff31 and hid-asus will map these in its input_mapping for all devices to which it binds (independent of any quirks). Add an event callback which check for unmapped (because sofar unknown) usages within the Asus Vendor UsagePage and log a warning for these. The purpose of this patch is to help debugging / find such unmapped codes and add them to the asus_input_mapping() function. Signed-off-by:
