Ideally speaking, the checks and the setups of those new bits should
be coupled with the PCM protocol version check (and the version
bump).
But it seems that you've already applied the series, and practically
seen, those bits should be either not set or harmless, so let's cross
fingers.
Exactly, the current kernel code should skip those new flags, so they are used
in alsa-lib only. It's just something like a "reservation" for the kernel
space until things are really used there. We can bump the protocol version
later (perhaps with other changes).
