    Subject[20/70] ARM: pxa: fix PGSR register address calculation
    2.6.39-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    From: Paul Parsons <lost.distance@yahoo.com>

    commit beb0c9b056b1c23d2029b46a425362e9ccbeba01 upstream.

    The file mfp-pxa2xx.c defines a macro, PGSR(), which translates a gpio
    bank number to a PGSR register address. The function pxa2xx_mfp_suspend()
    erroneously passed in a gpio number instead of a gpio bank number.
