already sent that one combined patch.

but this rule is really confusing me now .. :(
if i can understand the devicemodel then this rule should not be tough
to understand.
so, what i understood till now:
1) any patch of the series should not break the build.
	(you told me that in my parport patch series :) )

2) any patch of the series should not introduce build warning.

3) when i am modifying some line, i can make simple changes in style.
	but if its big change in style then that should be a separate
	patch.
