phy: mapphone-mdm6600: Fix PM error handling in phy_mdm6600_probe
stable inclusion from stable-v5.10.114 commit 9e00a6e1fd719a4021eb03bd7870e95bae2b4325 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5IY1V Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=9e00a6e1fd719a4021eb03bd7870e95bae2b4325 -------------------------------- [ Upstream commit d644e0d7 ] The pm_runtime_enable will increase power disable depth. If the probe fails, we should use pm_runtime_disable() to balance pm_runtime_enable(). And use pm_runtime_dont_use_autosuspend() to undo pm_runtime_use_autosuspend() In the PM Runtime docs: Drivers in ->remove() callback should undo the runtime PM changes done in ->probe(). Usually this means calling pm_runtime_disable(), pm_runtime_dont_use_autosuspend() etc. We should do this in error handling.
