suspend/hibernate/resume code in wireless drivers.

[Hin-Tak Leung <htl10@users.sourceforge.net>]

Hi,

I am just experiencing a problem I read about but I thought I didn't have.
I have always been able to suspend/resume without unloading the rtl8187 module ever since it started to work reasonably well. It seems that there is some automatic mechanism for unloading any usb network driver which does not have its own suspend/resume code. But it doesn't work in 2.6.27. 

(I filed this as https://bugzilla.redhat.com/show_bug.cgi?id=469461, and there is a reference to an upstream bug report).

Anyway, I think this is the likely breakage?

    USB: Force unbinding of drivers lacking reset_resume or other methods
    
    This patch (as1024) takes care of a FIXME issue: Drivers that don't
    have the necessary suspend, resume, reset_resume, pre_reset, or
    post_reset methods will be unbound and their interface reprobed when
    one of the unsupported events occurs.
    
    This is made slightly more difficult by the fact that bind operations
    won't work during a system sleep transition.  So instead the code has
    to defer the operation until the transition ends.
