4.9-stable review patch.  If anyone has any objections, please let me know.


From: Sean Young <s...@mess.org>

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.
