[31/32] drm: Nuke fb->bits_per_pixel

Commit Message

From: Ville Syrjälä <[e-mail]>

Replace uses of fb->bits_per_pixel with fb->format->cpp[0]*8.
Less duplicated information is a good thing.

Note that I didn't put parens around the cpp*8 in the below cocci script,
on account of not wanting spurious parens all over the place. Instead I
did the unsafe way, and tried to look over the entire diff to spot if
any dangerous expressions were produced. I didn't see any.

There are some cases where previously the code did X*bpp/8, so the
division happened after the multiplication. Those are now just X*cpp
so the division effectively happens before the multiplication,
but that is perfectly fine since bpp is always a multiple of 8.

Hi Ville,

Thank you for the patch.

Maybe just WARN_ON(fb->format->cpp[0] != 1); ?

I think you can remove the whole check.

The parentheses are not needed.

With these fixed,

I think I had a bit of cocci to do that... Yeah, it's there, and rerunning
it does clean this up.

spatch is rather finicky and does occasionally miss entire files when
you run it in the -dir mode. But in this case it clearly do something to
the file, so not sure why the cleanup part didn't get done.

Not sure I can tell the tool that. Probably easier to remove it by hand
afterwards.

Added by cocci. I guess I can tell it to clean that up, but have to
double check that it won't accidentally clean up something else too
which needs extra parens.
