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". Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=189021 Signed-off-by:Pan Bian <bianpan2016@163.com> Signed-off-by:
