From: Miaoqian Lin <linmq006@xxxxxxxxx>
[ Upstream commit 9c59a01caba26ec06fefd6ca1f22d5fd1de57d63 ]
pm_runtime_get_sync() will increment pm usage counter.
Forgetting to putting operation will result in reference leak.
Add missing pm_runtime_put_sync in some error paths.
Fixes: 9ac33b0ce81f ("CLK: TI: Driver for DRA7 ATL (Audio Tracking Logic)")
