Hi Greg,

Am resending this series with proper cover letter and subject-line.

Recently runtime pm testing on slimbus reveled that its
totally broken on SlimBus ngd drivers.

Below are the fixes to get it back working.

- One of the reason begin incorrect device pointer used for
runtime pm and in some places

- Second one (2 patches) was to do with unable to validate
transaction id which resulted in negative runtime pm count.

- Other fix was to do with resetting dma addresses once ngd
controller is power-cycled.

With all these fixed runtime pm is now fully functional on NGD
controllers.

Currently I marked them all with Cc: <stable@xxxxxxxxxxxxxxx>
as these all patches are required to fix runtime pm on SlimBus
NGD controller.

Can you please queue them up for next possible 5.14 rc.

thanks for you help,
srini
