Subject: crypto: omap-aes - Fix broken pm_runtime_and_get() usage
From: Heiner Kallweit <hkallweit1@xxxxxxxxx>
commit c2aec59be093bd44627bc4f6bc67e4614a93a7b6 upstream.
This fix is basically the same as 3d6b661330a7 ("crypto: stm32 -
Revert broken pm_runtime_resume_and_get changes"), just for the omap
driver. If the return value isn't used, then pm_runtime_get_sync()
has to be used for ensuring that the usage count is balanced.
