Subject: [media] lirc: LIRC_GET_REC_RESOLUTION should return microseconds
Date: Tue, 11 Jul 2017 10:47:37 +0100
Since commit e8f4818895b3 ("[media] lirc: advertise
LIRC_CAN_GET_REC_RESOLUTION and improve") lircd uses the ioctl
LIRC_GET_REC_RESOLUTION to determine the shortest pulse or space that
the hardware can detect. This breaks decoding in lirc because lircd
expects the answer in microseconds, but nanoseconds is returned.
drop at bump to 4.13
