[PATCH 6.12.y 1/2] ALSA: hda: cs35l41: Use auto-cleanup for put_device()

[Sasha Levin <sashal@kernel.org>]

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit c437a83cc69645edab8e0bfc450a3b706abe759e ]

A temporary refcount management of a struct device can be done
gracefully with __clean(put_device) for avoiding potential leaks.

No functional change but just a code cleanup.
