[PATCH 5.4 116/144] ASoC: wcd9335: Fix a memory leak in the error handling path of the probe function
From: Greg Kroah-Hartman
Date: Mon Sep 13 2021 - 09:32:12 EST
From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit fc6fc81caa63900cef9ebb8b2e365c3ed5a9effb ]
If 'wcd9335_setup_irqs()' fails, me must release the memory allocated in
'wcd_clsh_ctrl_alloc()', as already done in the remove function.
Add an error handling path and the missing 'wcd_clsh_ctrl_free()' call.
Fixes: 20aedafdf492 ("ASoC: wcd9335: add support to wcd9335 codec")
