From 3f56df4c8ffeb120ed41906d3aae71799b7e726a Mon Sep 17 00:00:00 2001 From: Sean Young Date: Mon, 9 Nov 2020 23:16:52 +0100 Subject: [PATCH] media: sunxi-cir: ensure IR is handled when it is continuous If a user holds a button down on a remote, then no ir idle interrupt will be generated until the user releases the button, depending on how quickly the remote repeats. No IR is processed until that point, which means that holding down a button may not do anything. This also resolves an issue on a Cubieboard 1 where the IR receiver is picking up ambient infrared as IR and spews out endless "rc rc0: IR event FIFO is full!" messages unless you choose to live in the dark.
