If anyone has any objections, please let me know. ------------------ From: Guangshuo Li [ Upstream commit 8061720f6be1811478914f8b6143778d70f6033f ] mma9551_probe() enables runtime PM autosuspend with pm_runtime_use_autosuspend(). The probe error path correctly undoes this setting with pm_runtime_dont_use_autosuspend(), but the normal remove path only disables runtime PM. The runtime PM API requires pm_runtime_use_autosuspend() to be undone with pm_runtime_dont_use_autosuspend() at driver exit unless runtime PM was enabled with devm_pm_runtime_enable(). Leaving the autosuspend flag set therefore leaves the runtime PM state incompletely cleaned up after the driver is unbound. Add the missing pm_runtime_dont_use_autosuspend() call to the remove path. This issue was found by manual code inspection.
