net: brcm80211: Deletion of unnecessary checks before two function calls
The functions brcmu_pkt_buf_free_skb() and release_firmware() test whether their argument is NULL and then return immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Acked-by: Arend van Spriel <arend@broadcom.com> Signed-off-by: John W.
