PATCH 1/1 GPU-host1x: Use a signed return type for do_relocs()

From: Markus Elfring <[email protected]>
Date: Sat, 19 Dec 2015 12:48:31 +0100

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

This issue was detected by using the Coccinelle software.
