From b35af4a7d7f1fd6af25d3068a00224477989d749 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 17 Feb 2020 17:39:45 +0300 Subject: [PATCH] io_uring: remove unnecessary NULL checks to #26323588 commit 297a31e3e8318f533cff4fe33ffaefb74f72c6e2 upstream. The "kmsg" pointer can't be NULL and we have already dereferenced it so a check here would be useless.
