Subject: ALSA: hda/ca0132 - Fix memory leak at error path
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cc91ceaf3efd9a2364463b5f85d9f391f1ddaa9d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ALSA: hda/ca0132 - Fix memory leak at error path

The CA0132 codec driver doesn't call the free function at its error
path of the probe, which leaves the allocated memory.  Call
ca0132_free() properly at the error handling.

Fixes: a73d511c4867 ("ALSA: hda/ca0132: Add unsol handler for DSP and jack detection")
