6.12-stable review patch. If anyone has any objections, please let me know.

From: Lubomir Rintel lrintel@redhat.com
commit cdef30e0774802df2f87024d68a9d86c3b99ca2a upstream.
This fixes data corruption when accessing the internal SD card in mass storage mode.
I am actually not too sure why. I didn't figure a straightforward way to reproduce the issue, but i seem to get garbage when issuing a lot (over 50) of large reads (over 120 sectors) are done in a quick succession. That is, time seems to matter here -- larger reads are fine if they are done with some delay between them.
But I'm not great at understanding this sort of things, so I'll assume the issue other, smarter, folks were seeing with similar phones is the same problem and I'll just put my quirk next to theirs.
The "Software details" screen on the phone is as follows:
V 04.06 07-08-13 RM-849 (c) Nokia
TL;DR version of the device descriptor:
idVendor 0x0421 Nokia Mobile Phones idProduct 0x06c2 bcdDevice 4.06 iManufacturer 1 Nokia iProduct 2 Nokia 208
The patch assumes older firmwares are broken too (I'm unable to test, but no biggie if they aren't I guess), and I have no idea if newer firmware exists.
