From 2837d7277ea10c4f596ac9fb908b158a9cdb7d19 Mon Sep 17 00:00:00 2001 From: Sean Young Date: Sun, 17 Oct 2021 13:01:15 +0100 Subject: [PATCH] media: ite-cir: IR receiver stop working after receive overflow commit fdc881783099c6343921ff017450831c8766d12a upstream. On an Intel NUC6iSYK, no IR is reported after a receive overflow. When a receiver overflow occurs, this condition is only cleared by reading the fifo. Make sure we read anything in the fifo.
