[PATCH AUTOSEL 4.14 33/56] media: igorplugusb: receiver overflow should be reported

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
