[PATCH AUTOSEL 5.15 114/188] media: igorplugusb: receiver overflow should be reported

From: Sasha Levin
Date: Mon Jan 17 2022 - 21:55:15 EST


From: Sean Young <sean@xxxxxxxx>

[ Upstream commit 8fede658e7ddb605bbd68ed38067ddb0af033db4 ]

Without this, some IR will be missing mid-stream and we might decode
something which never really occurred.
