Subject: [PATCH] crypto: omap-aes: Fix broken pm_runtime_and_get() usage
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit
Precedence: bulk

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.

Fixes: 1f34cc4a8da3 ("crypto: omap-aes - Fix PM reference leak on omap-aes.c")
