Subject: [PATCH 4/4] crypto: sun8i-ce-cipher - use pm_runtime_resume_and_get()

Replace pm_runtime_get_sync() usage with pm_runtime_resume_and_get() to
simplify error handling.

This is recommended in the documentation of pm_runtime_get_sync():
/**
 * pm_runtime_get_sync - Bump up usage counter of a device and resume it.
...
 * Consider using pm_runtime_resume_and_get() instead of it, especially
 * if its return value is checked by the caller, as this is likely to result
 * in cleaner code.
...
 */
