Subject: [patch] hwmon: (w83793) Clean up a signedness issue
Date: Sat, 19 Oct 2013 09:12:22 +0000	[thread overview]
Message-ID: <20131019091222.GF9312@longonot.mountain> (raw)

We cap the upper bound of "mtimeout" but since it's signed we should
check for negative values as well.  The mistake is harmless.  But I have
changed it to unsigned as a cleanup.
