Subject: [PATCH] staging-slicoss: Use a signed return type for
 slic_card_locate()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 19 Dec 2015 20:30:39 +0100

The return type "u32" was used by the slic_card_locate() function
despite of the aspect that it will eventually return a negative
error code.
Improve this implementation detail by using the type "s32" instead.

This issue was detected by using the Coccinelle software.
