[PATCH 0/4] slimbus: patches (set 1) for 5.15

Hi Greg,

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 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 5.15.

thanks for you help,
srini
