- about firmware cache:
- --------------------
- After firmware cache mechanism is introduced during system sleep,
- request_firmware can be called safely inside device's suspend and
- resume callback, and callers need't cache the firmware by
- themselves any more for dealing with firmware loss during system
- resume.
