[PATCH v3 0/7] Remove errors building drivers/DRIVERNAME

[Leonardo BrÃs]

Special thanks for the feedback from:
- Finn Thain (I fixed the build problem)
- Geert Uytterhoeven (The cross compilers were very useful)
- Rolf Eike Beer (Was unintentional, thanks for the help!)

This Patchset changes some driver's Makefile to allow them building
using the command 'make drivers/DRIVERNAME', if compatible.

The changed drivers would return error if the above command was run
on them, after an x86 allyesconfig.

The main reason of this patchset is to allow building lists of
drivers looking for warnings and errors to be fixed.

I see this change as a new feature, not a bugfix. I understand
the default bahavior may be building with a simple 'make', but I
believe adding this new possibility will not be harmful.

My main objective is to allow developers with low processing power
to do changes in the kernel and look bugs using free services like
GiltabCI, before submitting to community.

If there is any interest helping/using this, I have a prototype in:
