+Subject: [PATCH 1/2] media: sunxi-cir: ensure IR is handled when it is
+ continuous
+Date: Tue, 10 Nov 2020 09:15:56 +0000
+
+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.
