then probably the issue you have is another one though. The above
patch was commited upstream as 72741084d903 ("mmc: core: Fix init of
SD cards reporting an invalid VDD range") and landed in 5.3-rc7, and
got backported to several stable series as in 5.2.12, 4.19.70,
4.14.142, 4.9.191, 4.4.191 and 3.16.78.

The report did not contain any further information, so please do
attach as well kernel logs, errors, you are seeing, how/if the card is
detected (when filling the report via reportbug, this information will
be attached).

Regards,
Salvatore
