From ef899c0778a39063816e19d749a688c06a6ac78e Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Fri, 28 Aug 2015 21:35:14 +0300 Subject: [PATCH] phylib: simplify NULL checks Fix scripts/checkpatch.pl's messages like: CHECK: Comparison to NULL could be written "!phydrv->read_mmd_indirect" BTW, it doesn't detect the reversed comparisons (which I've fixed as well).
