I've attempted to make a change as you suggested but it turned out
that all regulators I'm adding supplies for in the second patch are
also used by the other, high resolution camera. It's not about I don't
want to follow you suggestions. The argument is that I's like to add shortly
support for the other camera and then the patch would be just one line
per a power supply rather than 4. I really don't mind to adhere to your
preferred style. But in this case it would be just more work to revert
things back and forth.

I've boot tested your patch:
ARM: S5PV210: Use REGULATOR_SUPPLY macro for regulator consumers
on Aquila and GONI board altogether with my changeset.

Thanks! I am going to post further patches for this board soon so there
should be no need to change anything. Please use you time for more important
things ;)

I've noticed one issue with the first patch, i.e. Kyungmin's email address
is broken. Should I resend the patch or could you please correct this on your side?

Thanks,
