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

The patch below was submitted to be applied to the 5.4-stable tree.
I fail to see how this patch meets the stable kernel rules as found at Documentation/process/stable-kernel-rules.rst.
I could be totally wrong, and if so, please respond to stable@vger.kernel.org and let me know why this patch should be applied. Otherwise, it is now dropped from my patch queues, never to be seen again.
thanks,

We will have the wl1251 defined as a child node of the mmc interface and can read setup for gpios, interrupts and the ti,use-eeprom property from there instead of pdata to be provided by pdata-quirks.
