Yeah, after implementing it in ath10k it seems there would
be very little over-lap, so probably each driver should just
do their own.

We can keep the debugfs file names the same, and the udev
event types the same, which should help user-space a bit.

I can get firmware logs, but they are not interleaved.
Probably good enough for now..and we can always add
printk or similar in the future if we all decide it's
useful.

Being able to look at your iwlwifi work made my patches lot easier,
so thanks for taking the initiative!

Thanks,
Ben
