Hello Ulf,
Red herring. Apparently the issue is not in the card reader driver but
in some other new kernel option. If I build the new (5.10.10) kernel
using the 5.7 config and make oldconfig giving no to all new things then
the cards are not detected. If I copy the 5.7 config and use make
xconfig and just save it then it works. I just wonder what this option
might be and why it is not selected automatically if it is required.
Kind regards.

Hello,
It seems there is some issue with the rtsx_usb module. I'm using Gentoo
with kernel 5.7.9 at the moment as the card reader driver does not work
with 5.9 and 5.10 kernels, I don't know if the issue is there with 5.8
kernels as it was causing issues with my vga, my card reader info below:
Bus 002 Device 002: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129
Card Reader Controller
The module detect the reader but does not detect the sd cards inserted,
the same cards work with 5.7 so I assume something was broken i the driver.
>From the drivers/mmc/host/rtsx_usb_sdmmc.c perspective, nothing has
changed for quite a while and likewise for
drivers/misc/cardreader/rtsx_usb.c.
However, I think you probably need to run a "git bisect" to point out
the offending commit. And it looks like you already have some good
starting point to use for the git bisect.
I have also looped in some of the developers from Realtek/Realsil,
please keep them in the loop, as they know this HW and driver.
Kind regards
