Normally we'd align the parameters like so:

			buf[i] = modifier((data_type)va_arg(args,		\
							    unsigned int));	\

Not properly aligned.

I feel like the original is basically OK but if we're going to change it
then align it like this:

	ret = fbtft_write_buf_dc(par, par->buf, sizeof(data_type) + offset,	\
				 0);						\


Etc.
