That's handled by the Intel team and the kbuild-bot.  However, I wasn't
able to compile the d29d41e28eea65 "ASoC: topology: Add support for ..."
commit because of a build error in other parts of the kernel.  I first
had to apply:

Fixes: 52a9dab6d892 ("libsubcmd: Fix use-after-free for realloc(..., 0)")

So maybe the build breakage messed up git bisect.  Not sure.
