Re: [PATCH v3 2/2] soundwire: dmi-quirks: drop the ghost RT1320 on the Surface Pro 11 (Intel)

Pierre-Louis,

Point taken on the length, and thank you for the MIPI WG history — that is
the part I had no way to find, and it settles what I was asking. I will
leave NEWLY_ATTACHED and HAS_BEEN_RESET alone.

On bisect: the status register is read before the condition is evaluated,
so no version of that test can change the value — bisecting the driver
would read the same thing throughout. What differs is the machine, two
months apart, and I cannot recreate July to walk between them. So it stays
unexplained, and by your account it does not need to be: only
NEEDS_INITIALIZATION matters, and first_hw_init OR the bit is what the
driver now does.
