Subject: 4.5 Regression - mouse not working after resume from suspend

There seems to be a regression in resuming my laptop from a suspend to RAM or disk. The symptom is that my bluetooth
mouse doesn't work after the resume. The kernel is built after a pull of Linus' tree this morning (v4.5-rc2-340-g5af9c2e).

Attached is the output from dmesg showing the boot, suspend (to RAM) and resume. You'll see that during the resume,
error -517 is being reported for some devices. Suspend/resume has worked perfectly with a 4.[234].x kernels.

I'll start a bisection, but thought I'd give a heads up in case someone can see the problem before I get done with the
bisect.

Chris
