4.4-stable review patch. If anyone has any objections, please let me know.
------------------
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.
