Subject: [PATCH AUTOSEL 4.19 24/39] ALSA: ppc: fix error return code in snd_pmac_probe()

From: Yang Yingliang <yangyingliang@...wei.com>

[ Upstream commit 80b9c1be567c3c6bbe0d4b290af578e630485b5d ]

If snd_pmac_tumbler_init() or snd_pmac_tumbler_post_init() fails,
snd_pmac_probe() need return error code.
