[PATCH 5.4 264/453] remoteproc: qcom: fix reference leak in adsp_start

[Greg Kroah-Hartman]

From: Zhang Qilong <zhangqilong3@xxxxxxxxxx>

[ Upstream commit aa37448f597c09844942da87d042fc6793f989c2 ]

pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to pm_runtime_put_noidle will result in
reference leak in adsp_start, so we should fix it.
