Subject: [PATCH] ASoC: SOF: Intel: Initialize chip in hda_sdw_check_wakeen_irq()
Date: Wed, 09 Aug 2023 11:12:07 -0700	[thread overview]
Message-ID: <20230809-intel-hda-missing-chip-init-v1-1-61557ca6fa8a@kernel.org> (raw)

Clang warns (or errors with CONFIG_WERROR):

  sound/soc/sof/intel/hda.c:423:6: error: variable 'chip' is uninitialized when used here [-Werror,-Wuninitialized]
    423 |         if (chip && chip->check_sdw_wakeen_irq)
        |             ^~~~
  sound/soc/sof/intel/hda.c:418:39: note: initialize the variable 'chip' to silence this warning
    418 |         const struct sof_intel_dsp_desc *chip;
        |                                              ^
        |                                               = NULL
  1 error generated.

Add the missing initialization, following the pattern of the other irq
functions.
