[PATCH] sound: oss: ad1848: Fix returned errno code in ad1848_init()

From: Luis de Bethencourt
Date: Tue Sep 22 2015 - 11:38:03 EST


The driver is using -1 instead of the -ENOMEM defined macro to specify
that a buffer allocation failed. Since the error number is propagated,
the caller will get a -EPERM which is the wrong error condition.

Smatch tool warning:
ad1848_init() warn: returning -1 instead of -ENOMEM is sloppy
