Subject: [PATCH] staging: gdm724x: remove redundant assignment to pointer 'w'

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

The pointer 'w' is being initialized with a value that is never read
and it is being updated later with a new value. The initialization
is redundant and can be removed.

Addresses-Coverity: ("Unused value")
