[PATCH 00/10] Fix a bunch more W=1 warnings in MFD

Attempting to clean-up W=1 kernel builds, which are currently
overwhelmingly riddled with niggly little warnings.

Lee Jones (10):
  mfd: wm8350-core: Supply description wm8350_reg_{un}lock args
  mfd: mfd-core: Complete kerneldoc header for devm_mfd_add_devices()
  mfd: db8500-prcmu: Add description for 'reset_reason' in kerneldoc
  mfd: db8500-prcmu: Remove incorrect function header from .probe()
    function
  mfd: omap-usb-host: Remove invalid use of kerneldoc syntax
  mfd: omap-usb-host: Provide description for 'pdev' argument to
    .probe()
  mfd: omap-usb-tll: Provide description for 'pdev' argument to .probe()
  mfd: atmel-smc: Silence comparison of unsigned expression < 0 is
    always false warning (W=1)
  mfd: atmel-smc: Add missing colon(s) for 'conf' arguments
  mfd: altera-sysmgr: Supply descriptions for 'np' and 'property'
    function args

GENMASK and it's callees conduct checking to ensure the passed
parameters are valid.  One of those checks is for '< 0'.  So if an
unsigned value is passed, in an invalid comparison takes place.

Judging from the current code, it looks as though 'unsigned int'
is the correct type to use, so simply cast these small values
with no chance of being false negative to signed int for
comparison/error checking purposes.

Why are all of these documentation fixes for stable?

Because they fix compiler warnings.

When you type 'make' these warnings show up?  We don't do documentation
builds as part of a normal build...

If for some reason we ever get rid of all of the thousands of current
warnings, then yes, I will be glad to consider stuff like this then.

thanks,

greg k-h

Not correct?

I am overjoyed to see people fixing docs build warnings, it is work that
is desperately needed.  That said, these warning fixes are probably not
stable material; the problem is bigger and longer-term than that.

'make W=1' yes. :)

Workin' on it!

Sorry for the noise (for now).

I'll do what I can with the time that I have.

The plan is to keep plodding on and seeing how far I can take it.  A
clean W=1 build sounds like rainbows and unicorns presently, but Rome
wasn't built in a day.

Tell you the truth, drafting patches (again, after a break) is a
welcome change/release from digging around and reviewing Android
Stable patches.  It's the only thing keeping me sane. :)

That said, these warning fixes are probably not
stable material; the problem is bigger and longer-term than that.

Fair enough.

GENMASK and it's callees conduct checking to ensure the passed

Judging from the current code, it looks as though 'unsigned int'
is the correct type to use, so simply cast these small values
with no chance of being false negative to signed int for
comparison/error checking purposes.

I've been thinking about that one but shouldn't the proper fix be in
GENMASK? My understanding is that this happens because l is 0 and I
don't think GENMASK would ever expect negative number. What about simply
checking that h != l when l is 0?

Looks like Rikard Falkeborn recently submitted a patch to 'fix' this
issue.  However, Linus slammed it, decrying that it's the warning
that's wrong, not the code.  Looks like the type-limits warning might
be getting downgraded to W=2 instead (although I don't see a patch
yet).

I'm going to drop this patch.
