Re: [linux-pm] rtl8187 usb wifi adaptor causes suspend hang

[Larry Finger <Larry.Finger@lwfinger.net>]

Here is a second try at a suspend/resume patch for rtl8187. This one
also seems a bit too easy; however, it did work for me, at least for
STD. I now realize that my machine didn't power off in my previous
test. This time I manually turned it off before restarting. My
computer still doesn't STR, thus that was not tested.
