From 532298b95075144bcccf56d792f3fb3fbef2d5d0 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 11 Dec 2017 13:54:27 +0300 Subject: [PATCH] platform/x86: dell-wmi: check for kmalloc() errors This allocation won't fail in the current kernel because it's small but not checking for kmalloc() failures introduces static checker warnings so let's fix it.
