Your patch - pxa2xx-mfp2.patch - doesn't introduce any problems, but
I never had a failure case that could be used to prove the patch fixes
the direction/PGSR window bug. In theory the patch *should* fix it.
As for restoring the GPIO levels via GPSR and GPCR, that does seem
to work. Certainly the regular GPIO (AF0) outputs have their levels
restored OK.
Regards,
Paul
