Subject: [PATCH 3/3] usb: renesas_usbhs: Remove dummy runtime PM callbacks

From: Jarkko Nikula <[email-masked]>
Date: Wed, 24 Oct 2018 16:51:34 +0300

Platform drivers don't need dummy runtime PM callbacks that just return
success in order to have runtime PM happening. This has changed since
following commits:

05aa55dddb9e ("PM / Runtime: Lenient generic runtime pm callbacks")
543f2503a956 ("PM / platform_bus: Allow runtime PM by default")
8b313a38ecff ("PM / Platform: Use generic runtime PM callbacks directly")
