From ac96ce83ff21c9338afa0e81baabd902d9350015 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Thu, 20 Nov 2014 16:42:51 +0100 Subject: [PATCH] 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 Acked-by: Arend van Spriel Signed-off-by: John W.
