[alsa-devel] [PATCH 02/21] ASoC: sun4i-i2s: Switch to devm for PCM register

From: Maxime Ripard <maxime.ripard at bootlin.com>

Since the introduction of the driver, a new managed helper for the
dmaengine PCM registration has been created. Let's use it to simplify a bit
our probe and remove functions.
