Hi, Takashi
I use git to generate patches. (I run git-fetch origin, git-fetch-rebase
origin, and git-format-patch origin)

There are two patch, one for the addition of HDMI, and one for the fix
for our aza controller.

Please check it.

Thanks

OK, then could you split the patch to separate ones, i.e. one for the
fix for this problem regarding Nvidia controller chip, and one for the
addition of HDMI?

Don't forget to add a proper description for each patch, please ;)

As mentioned, that flag is a last resort, and I think it can be fixed
in a saner way.  But, the flag is surely safe, and we can track down
the problem later on.


thanks,

Takashi
