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.

Why do you want these for 5.15-rc1 when you need them to fix problems in
5.14? Shouldn't they go into 5.14-final?

Yes, these should go to other stable trees aswell.
I assumed that Fixes tag will automatically backport those patches.


confused,
Sorry if I confused you.
