[PATCH 4.19 031/323] wl3501_cs: Remove unnecessary NULL check

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Alex Dewar <alex.dewar90@xxxxxxxxx>

[ Upstream commit 1d2a85382282e7c77cbde5650335c3ffc6073fa1 ]

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.
