[PATCH] crypto: sun8i-ce - Fix runtime PM imbalance in sun8i_ce_cipher_init

From: Dinghao Liu
Date: Sun Jun 21 2020 - 22:40:49 EST


pm_runtime_get_sync() increments the runtime PM usage counter even
the call returns an error code. Thus a corresponding decrement is
needed on the error handling path to keep the counter balanced.

Fix this by adding the missed function call.
