Subject: media: lirc: always send timeout reports Author: Sean Young <[email protected]> Date: Sat Nov 27 12:46:58 2021 +0100 Without timeout reports, it is impossible to decode many protocols since it is not known when the transmission ends. timeout reports are sent by default, but can be turned off. There is no reason to turn them off, and I cannot find any software which does this, so we can safely remove it. This makes the ioctl LIRC_SET_REC_TIMEOUT_REPORTS a no-op.
