Subject[PATCH] staging: rtl8192u: remove redundant null check on array 'data'
Date
From: Colin Ian King <colin.king@canonical.com>

The NULL check on ram->u.wpa_ie.data is redudant as data is
zero-length array and is not a pointer, so it can't be null.
Remove the check.

Addresses-Coverity: ("Array compared against 0")
