Subject: Re: [PATCH] bcma: s&r: NULL mapped core

Yup. This definitely helps.

I haven't done a lot of suspend/resume cycles, and I have my own
cleanups in my tree, but with this, I finally get a successful resume.

I'll send out a series of cleanups and fixes that will include this.
Can you test whether my series works for you too?
