From 7cf6156633b71743c09a8e56b1f0dedfc4ce6e66 Mon Sep 17 00:00:00 2001 From: Pan Bian Date: Sun, 4 Dec 2016 13:45:15 +0800 Subject: [PATCH] atm: fix improper return value It returns variable "error" when ioremap_nocache() returns a NULL pointer. The value of "error" is 0 then, which will mislead the callers to believe that there is no error. This patch fixes the bug, returning "-ENOMEM".
