[PATCH 1/1] atm: fix improper return value

2016-12-03 Thread Pan Bian
From: Pan Bian 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". Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=189021
