Ah, my apologies - I had mis-interpreted the reversion as applying to
the SRU. I've no issue with a reversion in hirsute, provided it doesn't
delay existing users from using their Bluetooth hardware.

I estimate, as I think several others do judging by various comments,
that the patches in their current state don't stand much chance of
passing muster upstream, and I have no desire to waste their time with a
premature submission. At the very least, some justification needs adding
to the 1 second sleep: either a datasheet reference, which I've so far
failed to find, or some empirical measurements that it's actually
required (which I'm in the process of gathering; I've verified *a* delay
is required but not the minimum, or whether it can be combined with the
post-load nanosleep), along with evidence it doesn't break any existing
platforms (I've found a datasheet reference to back that bit up, but
tests are good too).

Anyway, sorry I mis-interpreted the release your action applied to; I
look forward to seeing the SRU land.

In the meantime, rest assured a submission will be made upstream as soon
as I think I've got a faint hope of it passing!
