From 3e7fb9f7ec00fd7cefd0d8e83df0cff86ce12515 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sun, 28 Dec 2008 16:47:30 +0100 Subject: ALSA: Return proper error code at probe in sound/isa/* Some drivers in sound/isa/* don't handle the error code properly from snd_card_create(). This patch fixes these places.
