[PATCH 4.9 037/134] ASoC: cs42l56: fix up error handling in probe

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: 2021-03-01 17:50:00
Also in: lkml
Subsystem: cirrus logic audio codec drivers, sound, sound - soc layer / dynamic audio power management (asoc), the rest · Maintainers: David Rhodes, Richard Fitzgerald, Jaroslav Kysela, Takashi Iwai, Liam Girdwood, Mark Brown, Linus Torvalds

From: Dan Carpenter <redacted>

[ Upstream commit 856fe64da84c95a1d415564b981ae3908eea2a76 ]

There are two issues with this code.  The first error path forgot to set
the error code and instead returns success.  The second error path
doesn't clean up.

Fixes: 272b5edd3b8f ("ASoC: Add support for CS42L56 CODEC")
