Did you also run 'make check && make syntax-check' on this patch? Because it
fails for me.

...and it fails because for ^this you also need to define the capability in
qemu_capabilities.c in the hunks below. However, the capabilities XML files are
updated in patch 2, so this first patch naturally fails qemucapabilities test.
So, the two hunks below (qemu_capabilities.X) need to go back to the second
patch as you had it in the earlier versions.
With ^this change above though, you have two options:
1) move it to patch 2 as well, since we use type 'int' here in the switch
instead of type 'enum' which would normally fail because of -Wswitch-enum GCC
option.
2) be consistent, pretend it's an enum and would fail the compilation if it was
missing and return a temporary value, e.g. 0 instead of QEMU_CAPS_HDA_OUTPUT
and then in patch 2, you change this to QEMU_CAPS_HDA_OUTPUT, since in patch 2
you already have that one defined.
I'd personally go with option n.1), since it's easier and it's not worth to
spend any more time on it than necessary.

Like I mentioned above, ^these 2 hunks need to go back in patch 2 where you add
the tests/qemucapabilities files.
