Re: [PATCH] bus: fsl-mc: set dma_mask for the root DPRC device

Hi Ioana,

quoted

Fixes: a259ed1618d2 ("bus/fsl-mc: support dma configure for devices on fsl-mc bus")

Is this fixing an actual bug introduced by the blamed commit or are we
talking only about the warning message?

It is just a warning message.

I did more test today. I reverted it on my LX2160A with the SMMU-less config and rebooted.
Then, I get this notification:
  dprc.1: DMA mask not set

Still the DPRC binds, all DPAA2 children (dpni/dpio/dpbp) probe.

In practice, it is more a cleanup warning/notification. I do not remember why I did state
this commit log that is few month old.

I'll rework the v2 per your suggested common block, I'll drop Cc: stable and update
my commit log accordingly.

Best regards,
  Vincent

Commit 4d8bde883bfb ("OF: Don't set default coherent DMA mask") is the
one that added the dev_warn.
