Subject: media: mceusb: set timeout to at least timeout provided
Author: Sean Young <sean@xxxxxxxx>
Date: Fri Sep 2 12:32:21 2022 +0200
By rounding down, the actual timeout can be lower than requested. As a
result, long spaces just below the requested timeout can be incorrectly
reported as timeout and truncated.
