Subject: [PATCH] ASoC: SOF: Intel: fix hda_sdw_check_wakeen_irq()
Date:   Mon, 14 Aug 2023 09:46:29 +0200

From: Arnd Bergmann <arnd@arndb.de>

This function cannot work, as the 'chip' variable is never initialized:

sound/soc/sof/intel/hda.c:423:6: error: variable 'chip' is uninitialized when used here [-Werror,-Wuninitialized]
        if (chip && chip->check_sdw_wakeen_irq)
            ^~~~

Set it the same way that other functions in this file do.

There hasn't been a new linux-next in a few days, so there is a good chance
someone else already fixed this in the meantime. Sending out my fix in case
that hasn't happened yet.
