[PATCH 6.1 074/193] mmc: sunxi-mmc: Fix clock refcount imbalance during unbind

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Samuel Holland <samuel@xxxxxxxxxxxx>

commit 8509419758f2cc28dd05370385af0d91573b76b4 upstream.

If the controller is suspended by runtime PM, the clock is already
disabled, so do not try to disable it again during removal. Use
pm_runtime_disable() to flush any pending runtime PM transitions.

Fixes: 9a8e1e8cc2c0 ("mmc: sunxi: Add runtime_pm support")
