From 0953a2e33b0fca7db82081f85eb7ed6b4b76a669 Mon Sep 17 00:00:00 2001 From: Leo Kim Date: Wed, 27 Jan 2016 11:50:25 +0900 Subject: [PATCH] staging: wilc1000: wilc_frmw_to_linux(): fixes null check Null checking wilc_netdev and skb->dev are already done in the begining of the function and they are just print printing error log, so delete them. Null checking wilc is needed before is used so add null ckeck before it is used.
