You can't invoke vic_load_firmware() while RPM is suspended. Either
replace this with RPM get/put or do something else.

Why not, I'm not seeing any HW accesses in vic_load_firmware? Although
it looks like it might race with the vic_load_firmware call in
vic_runtime_resume which probably needs to be fixed.

It was not clear from the function's name that h/w is untouched, I read
"load" as "upload" and then looked at vic_runtime_resume(). I'd rename
vic_load_firmware() to vic_prepare_firmware_image().

And yes, technically lock is needed.

Yep, I'll consider renaming it.
