Thank you for providing a patch, and making Ubuntu better.
Can you provide some information on the status of the patch with regards
to getting it merged upstream? Has it been sent upstream, what sort of
feedback has it received, is it getting applied to a subsystem
maintainer's tree, etc?
People affected by this bug are probably wondering why the kernel team
doesn't just apply the patch and fix it. The reason is that the kernel
team is reluctant (not opposed) to apply any patch to a stable kernel
that is not from upstream. Applying patches that don't come from
upstream add greatly to the support of the kernel as other upstream
patches may touch the same area as the non-upstream patch and may
prevent them from applying cleanly.
To submit your patch, send your patch with the detailed
description/changelog and your Signoff (ending with Signed-off-by: your
name <email>), to the emails listed from ./scripts/get_maintainer.pl
drivers/SUBSYSTEM-DETAILS (the get_maintainer.pl is from the kernel
sources). Once you have sent the patch upstream and it's accepted,
please drop a note here so that we can cherry-pick/include the patch
into Ubuntu kernel.

Title:
Realtek Card Reader not working (kernel driver)
Status in linux package in Ubuntu:
Triaged
Bug description:
This is the situation if I use the normal 4.13 kernel driver
[ 1899.245301] mmc0: cannot verify signal voltage switch
[ 1899.377540] mmc0: new ultra high speed SDR104 SDXC card at address e624
[ 1899.401829] mmcblk0: mmc0:e624 AGGCE 59.5 GiB
[ 1899.404700] mmcblk0: p1
[ 1899.620084] mmcblk0: error -110 sending status command, retrying
[ 1899.620231] mmcblk0: error -22 sending status command, retrying
[ 1899.620419] mmcblk0: error -22 sending status command, aborting
[ 1899.905535] mmc0: cannot verify signal voltage switch
[ 1900.136253] mmcblk0: error -22 sending status command, retrying
[ 1900.136396] mmcblk0: error -22 sending status command, retrying
[ 1900.240070] mmcblk0: error -110 sending status command, aborting
[ 1900.240084] print_req_error: I/O error, dev mmcblk0, sector 8
but it works perfectly if I use the patched driver on kernel 4.4-4.7
this one https://github.com/Zibri/Realtek-rts5229-for-4.4-kernel
the problem is that I can't compile it on 4.13 and anyway this
affects a lot of systems using 5229/5227
many laptops use this.
any solution??
