Subject: [PATCH] media: lirc: LIRC_GET_REC_RESOLUTION should return
microseconds
References: bnc#1060662
Patch-mainline: 4.12.6
Git-commit: 9f5039ba440e499d85c29b1ddbc3cbc9dc90e44b
commit 9f5039ba440e499d85c29b1ddbc3cbc9dc90e44b upstream.
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.
