Subject: [PATCH] iio-light: Use a signed return type for ltr501_match_samp_freq()
Date: Sat, 19 Dec 2015 14:23:25 +0100	[thread overview]
Message-ID: <56755A4D.7000406@users.sourceforge.net> (raw)

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 19 Dec 2015 14:14:54 +0100

The return type "unsigned int" was used by the ltr501_match_samp_freq()
function despite of the aspect that it will eventually return a negative
error code.
Improve this implementation detail by deletion of the type modifier then.

This issue was detected by using the Coccinelle software.
