From: Arnaldo Carvalho de Melo Date: Thu, 24 May 2018 14:20:39 +0000 (-0300) Subject: perf tools: No need to check if the argument to __get() function is NULL X-Git-Tag: v4.18-rc1~72^2^2~46 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=362379aad56fdc627a49e30d12c3ece900221898;p=thirdparty%2Fkernel%2Flinux.git perf tools: No need to check if the argument to __get() function is NULL Those functions always check if the argument is NULL before trying to grab a reference count, and also will return the received object, so, to make code more compact, no need to check for NULL.
