Subject: RE: [PATCH v4 20/29] scsi: hpsa: use generic power management

-----Original Message-----

Switch to the new generic framework by updating function signatures and define a "struct dev_pm_ops" variable to bind PM callbacks. Also, remove unnecessary calls to the PCI Helper functions along with the legacy .suspend & .resume bindings.

Signed-off-by: Vaibhav Gupta <vaibhavgupta40@...il.com>

Acked-by: Don Brace <don.brace@...rochip.com>

I thought that I had given my Acked-by on 10/27, but it must have been lost.

Thanks for your attention to hpsa,
Don
