Right. How about the patch below? This one just moves the call

This is a patch to be applied after
"mmc: Test bus-width for old MMC devices (v2)"
and a replacement for the previous "mmc: Enable bus-width tests on
SDHCI host" patch. Instead of enabling all for sdhci, this one turns
on the feature only

Please drop this patch.
After a short discussion with Philip, we concluded that it&
In the patch "mmc: Add support for JMicron 388 SD/MMC controller",

Hi,
this is a patch series to add the support for the new JMicron 388
SD/MMC controller. The first patch is to add the support for the new
PCI device, including the quirks to handle different voltages per
medium.
The second patch is for improving the handling of different bus-
widths dynamically
