Subject[PATCH v2] ASoC: Intel: Skylake: prevent memory leak in snd_skl_parse_uuids
Date
In snd_skl_parse_uuids if allocation for module->instance_id fails, the
allocated memory for module shoulde be released. I changes the
allocation for module to use devm_kzalloc to be resource_managed
allocation and avoid the release in error path.

Changes in v2:
- Changed the allocation for module from kzalloc to devm_kzalloc
