stable inclusion from stable-5.10.65 commit 8ce22f85381f7bc16dd6be7e85143a25d1b30687 bugzilla: 182361 https://gitee.com/openeuler/kernel/issues/I4EH3U
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 19f479c37f76e926a6c0bec974a4d09826e32fc6 ]
Add missing pm_runtime_disable() when probe error out. It could avoid pm_runtime implementation complains when removing and probing again the driver.
Fixes:a94aec035a122 ("ASoC: mediatek: mt8183: add platform driver")
