Looks like this needs 5846efac138a ("mmc: sdhci-esdhc-imx: fix defined
but not used warnings"), but that's not quite right either as it fixes a
different change here, and only applying it still will result in a build
error.  I'll just drop the offending commit here entirely and wait for a
working set of patches to be submitted if the authors want them.

Same for the other branches where this showed up, thanks for the report.

thanks,
