media: imon: Add iMON VFD HID OEM v1.2 key mappings

[PATCH] media: imon: Add iMON VFD HID OEM v1.2 key mappings

Posted by Alessandro Baldi 1 week ago

Add Vol+/Vol-/Mute panel button mappings for iMON VFD HID OEM v1.2.
This version differs in the codes that generate the
KEY_VOLUMEUP, KEY_VOLUMEDOWN and KEY_MUTE events.

Note: this is my first kernel contribution.
Keycodes discovered by parsing USB packets with usbmon:
- modprobe usbmon
- cat /sys/kernel/debug/usb/usbmon/1u | grep Ii
Tested on Thermaltake Mozart Sx case with LibreELEC media center.
