Subject: [PATCH] wl3501_cs: Remove unnecessary NULL check
Date:   Sat, 26 Sep 2020 18:45:58 +0100

In wl3501_detach(), link->priv is checked for a NULL value before being
passed to free_netdev(). However, it cannot be NULL at this point as it
has already been passed to other functions, so just remove the check.
