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

From: Don.Brace
Date: Wed Nov 04 2020 - 13:08:42 EST


-----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.

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
