[BUG] mfd: rtsx_usb data corruption with SDCX microsd

[Marcus Overhagen]

I tested again with a 4.2 kernel but the bug is still present and
happens more often. So far nobody has responded.
I don't know what to do, and whether it's related to usb, mmc or mfd.
Please advise.

When using the RTS5129 card reader (USB2 but internal to Samsung
NP7230U3E series 7 ultrabook) and a Samsung 128 GB SDXC microsd the
data that is read or written is always corrupted.
A 32 GB SDHC does not show data corruption with this card reader.

Can somebody help me with this issue? Linux is corrupting data when
using the SD card reader!

I already sent it to linux-mmc on September 11th, and on September
17th forwarded it to Roger Tseng (author of rtsx_usb) and Samuel Ortiz
(maintainer of MFD) but have received no response,

I have a data corruption problem with RTS5129 sd card reader and a
128GB Samsung EVO microsd.

This is not a fake card, its tested ok with H2testw in another windows machine.
The card also works when I put it in an external microSD=>USB card reader.

Previously I was using a 32 GB Sandisk Ultra microsd UHS-I without
noticing any issues.
With the 128GB card, playback of dashcam videos shows many broken
frames, but is ok when using external card reader.

A test with F3 software shows "overwritten" sectors, I think in this
case they indicate that the wrong sector is read.

after unmounting and mounting it again, the result is different:

I got the impression yesterday that writing to the card results in
much more errors.
Thus today for this tests, data on the card was written with the other
windows machine and is 100% correct.

What can I do? What other information should I provide?

And this is when I tested the microSD card with another machine using
H2testw in windows and it's ok:

> Achtung: Nur 122590 von 122591 MByte getestet.
> Fertig, kein Fehler aufgetreten.
> Sie kÃnnen die Testdateien *.h2w jetzt lÃschen oder nach Belieben
