[alsa-devel] [PATCH v2 12/12] ASoC: SOF: Intel: hda-codec: fix memory allocation

[Pierre-Louis Bossart]

From: Libin Yang <libin.yang at intel.com>

Align all users of the hdac library to use devm_kzalloc.

Note for backports/stable: the patch ("ALSA: hdac: fix memory release
for SST and SOF drivers") needs to be applied as well.

Fixes: 5507b8103e26 ("ASoC: SOF: Intel: Add support for HDAudio codecs")
