At each patch / commit, the build must be kept successful.
In your case, in the patch 1, you introduced the new driver stuff to
Kconfig and Makefile while there is no actual code for that yet (which
will be added in later patches). This breaks the build at this
commit (lacking tas2781_hda_spi.c and co), and it's not acceptable.
You have to split patches in sensible manners; those to be logically
split, and yet they must not break builds.
thanks,
Takashi
