category: bugfix

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=bce5808fc95dbc8604e55a311881f04c5a9a37d6



--------------------------------

commit 20b794dd upstream.

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.

Fixes: 877f1a7c ("media: rc: mceusb: allow the timeout to be configurable")
