From c7c6f63dbc676788f0cb5a804dff57a0639af446 Mon Sep 17 00:00:00 2001 From: Sean Young Date: Fri, 7 Jul 2017 18:49:18 -0300 Subject: [PATCH 1/1] media: lirc: LIRC_GET_REC_RESOLUTION should return microseconds 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.
