Subject: iio-light: Use a signed return type for ltr501_match_samp_freq()

From: Markus Elfring <elfring@users.sourceforge.net>

commit c08ae18560aaed50fed306a2e11f36ce70130f65 upstream.

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.
