My 15c2:0036 device floods syslog when a keypad key is pressed:
Feb 18 19:00:57 homeserver kernel: imon 5-1:1.0: imon_incoming_packet: unknown keypress, code 0x100fff2
Feb 18 19:00:57 homeserver kernel: imon 5-1:1.0: imon_incoming_packet: unknown keypress, code 0x100fef2
Feb 18 19:00:57 homeserver kernel: imon 5-1:1.0: imon_incoming_packet: unknown keypress, code 0x100fff2
Feb 18 19:00:57 homeserver kernel: imon 5-1:1.0: imon_incoming_packet: unknown keypress, code 0x100fff2
Feb 18 19:00:57 homeserver kernel: imon 5-1:1.0: imon_incoming_packet: unknown keypress, code 0x100fff2
This patch lowers severity of this message when key appears to be coming from keypad.
