category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5ISAH

--------------------------------

[ Upstream commit 3d0b93d9 ]

If the device is already in a runtime PM enabled state
pm_runtime_get_sync() will return 1.

Also, we need to call pm_runtime_put_noidle() when pm_runtime_get_sync()
fails, so use pm_runtime_resume_and_get() instead. this function
will handle this.
