Right, I agree. We should fix the warning anyway.

If controller does not support cmd19 & cmd14, here is workaround we using.
Send just in case somebody require.

Subject: [PATCH] mmc: workaround of 1-bit mmc card
Chris,
It is not possible for bus_width to be not initialized. This would imply
ARRAY_SIZE(bus_widths) is 1. Certainly not true.
We could just initialize by changing
+ unsigned idx, bus_width;
to
+ unsigned idx, bus_width = 0;
I wonder what compiler are you using s

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 for JMicron, just to
