[PATCH] staging: greybus: Replace format specifiers

[pavankumaryalagada]

From: Yalagada Pavan Kumar <pavankumaryalagada@gmail.com>

Unsigned variables are printed using %d.
Replace them with %u to match their types.

I have reviewed every one of these and they look good.  Quite a few
of them--because the size of the value being formatted is less than
32 bits--would print correctly no matter what their value.  But I
think it at least does no harm to convert the format specifier to
unsigned in all of these cases.

I have highlighted below an existing bug that should be fixed.  It
gives an example of something to look for when you do this sort of
activity.  Please arrange to get that bug fixed.

I also pointed out one other observation for you to think about.

Thanks for sending this.  I didn't check to find any other instances
you might have missed, but you seem to have found quite a few.

This line actually contains an error (and it was there before).

The type of gb_bootrom_firmware_size_response->size is __le32.
So the value being formatted needs to be converted into CPU
byte order before being used.  That could be done this way:
	le32_to_cpu(size_response->size)
or just use this, which is known from a few lines above to
have the proper value and byte order:
	bootrom->fw->size

Please add this to your list of things to fix, and submit it
as a separate patch.  This would be a bug fix, which would
also give you a little bit of a new experience.

The above size calculation was done somewhere else without the
(int) cast, and the format specifier was %zu in that case.
I don't think this needs to be changed necessarily, but it's
something inconsistent across the Greybus code.  Consistency
helps readability and maintainability.

I was suprised the compiler doesn't complain about this.  It seems to
complain a lot about type-related format specifiers.  Yalagada maybe it
could be worth adding something clearly invalid in one of the argument
lists to see if the code is actually getting compiled, or if you need to
set some config option to make that happen.

Does anyone on the greybus list know anything about this person:

Bryan O'Donoghue <pure.logic@nexus-software.ie>

The email address is not valid, which is somewhat tiresome...

Bryan was on the Greybus kernel team.  Remove that address from
