Subject: [PATCH] video: fbdev: atyfb: Remove assigned but never used variable statements

From: Colin Ian King <colin.king@...onical.com>

There are a couple of statements where local variables are being assigned
values that are never read because the function returns immediately after
the assignment. Clean up the code by removing them.

Addresses-Coverity: ("Unused value")
