Subject: [PATCH] ASoC: codecs: aw88395: Uninitialized variable bug in aw_dev_parse_dev_type_v1()
Date: Mon, 6 Feb 2023 16:58:37 +0300	[thread overview]
Message-ID: <Y+EHjQ0+QCAXxmlh@kili> (raw)

The "cur_scene_id" variable is never initialized.  It needs to be set
to zero for the code to work.

Fixes: 4345865b003b ("ASoC: codecs: ACF bin parsing and check library file for aw88395")
Signed-off-by: Dan Carpenter <error27@gmail.com>
---
Presumably this code was tested with CONFIG_CC_HAS_AUTO_VAR_INIT_ZERO=y
or whatever to automatically initialize it to zero or it would have died
specatularly.  ;)
