Hi Greg,
I have checked with Documentation/process/stable-kernel-rules.rst but not found out
what is failing.
Basically this belongs to a series to fix a bug
81eef6ca9201 ("mmc: omap_hsmmc: Use dma_request_chan() for requesting DMA channel")
that exists since v4.7 and has been hidden by patches which came into the kernel over
the time.
BR and thanks,
Nikolaus Schaller
