Querying LE tx power on startup broke Bluetooth on some Broadcom chips
in Apple computers (at least MacBookPro16,1 and iMac20,1). Added a quirk
disabling this query for affected devices, based off their common chip
id 150. Affected devices will not be able to query LE tx power, however
they were not doing this before.

FWIW, if you need to respin this for some reason, could you do me a
favour and add the following after the "Fixes" line please:

Link:

That makes is easier to find related discussions and rationale behind a
certain change, as explained here:
https://www.kernel.org/doc/html/latest/maintainer/configure-git.html

This line is not crucial, but it makes my life easier as well, as I
slowly start to track regressions again. And this time I'm doing it with
the help of a software I wrote just for this purpose. I used your report
as one of the first few to give this "regzbot" a test, hence the issue
can now be seen in the webinterface (which is still a bit ugly, but it
does the job):

https://linux-regtracking.leemhuis.info/regzbot/mainline.html

And the thing is: when regzbot sees a patch with above Link:-tag hit
mainline it will automatically mark the issue as resolved, saving me
some work.

Thx!
