Subject: [PATCH] net: b44: remove redundant assignment to variable reg

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

The variable reg is being assigned a value that is never read
and is being re-assigned in the following for-loop. The
assignment is redundant and hence can be removed.

Addresses-Coverity: ("Unused value")
