Issue with pxa_dma driver on linux 4.4.y

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Dear maintainers,

In the tagging of fixing commits, I have submitted this patch which was merged
into the stable tree :
 - 6bab1c6afdca ("dmaengine: pxa_dma: fix the maximum requestor line")
which translated into this commit in the stable tree :
 - 94d75e190f19 ("dmaengine: pxa_dma: fix the maximum requestor line")

Unfortunately I have not tagged the dependant patches this one relies on, and
more specifically :
 - build breakage fix :
   - c283e41ef324 ("dmaengine: mmp-pdma: add number of requestors")
 - functionality breakage fix :
   - 72b195cb7162 ("ARM: pxa: add the number of DMA requestor lines")
   - 4c35430ad18f ("ARM: pxa: fix the number of DMA requestor lines")

I see 2 ways out of this situation :
 - either we revert stable commit 94d75e190f19
   => functionnality will remain broken, but only for a subset of DMA lines
 - or apply the dependant patches, ie. c283e41ef324, 72b195cb7162, 4c35430ad18f

It's up to you, but if you could choose one and apply it, the build breakage
will be gone.

I must mention that there is no defconfig file so far with covers this specific
build, and this was seen by Andrea who reported the issue.

Cheers.
