[PATCH v2 0/2] ASoC: mediatek: fix use-after-free in driver remove path

From: Trevor Wu
Date: Wed May 31 2023 - 23:33:35 EST


These patches concern modifications made in mt8186[1]. The clock
unregistration mechanism used in mt8188 and mt8195 is similar with
mt8186, resulting in the same problem existing within the driver.
Therefore, the solution has also been applied to these two platforms.

Changes since v1:
- remove unnecessary cast
