Subject: [PATCH 1/1] atm: fix improper return value
Date: Sun, 4 Dec 2016 13:45:15 +0800 [thread overview]
Message-ID: <1480830315-4924-1-git-send-email-bianpan201603@163.com> (raw)
From: Pan Bian <bianpan2016@163.com>
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".
