Oh weird. I'd hope that patch just wouldn't have applied in that case
instead of appearing successful.

I was using a newer branch that also included some other fixes I'm
working on, so not surprised the line numbers didn't match up. I'll
rebase future patches to v6.19-rc1.

I've got a new proposal about ready that just drops the slot specific
lock/unlock and save/restore instead. We kind of need to do that since
slot reset breaks devices with more than 8 functions. I'll send the
patch with the details in a few minutes.
