Bug#983672: linux-image: fails to recognize certain microSD cards

[José Luis González <bugs.jlg@gmail.com>]

Package: linux-image-4.19.0-13-amd64
Version: 4.19.160-2
Tags: patch upstream

Certain SD cards set a flag that isn't really defined in the SD spec
but the mmc should be ignoring. It turns out it doesn't, so the cards
don't get recognized properly making it impossible to use them.

There is a bug reported in kernel.org's bugzilla that explains it all:

https://bugzilla.kernel.org/show_bug.cgi?id=202473

Contained is a very small patch that fixes the problem:

https://patchwork.kernel.org/project/linux-mmc/patch/20190827081043.15443-1-ulf.hansson@linaro.org/

Please, incorporate the patch so that we can use these cards.

I have tested both version 4.19.160-2 and version 5.9.15-1~bpo10+1
(this from buster-backports), and neither mount my card successfully so
I understand the patch isn't incorporated to either.

I'd very much appreciate if the fix got into buster-backports.

Thank you so much in advance.
