[GIT PULL v2] MFD: Fixes due for the v3.10 -rc:s

[Lee Jones]

Hi Sam,

Since v1 of my MFD -fixes pull-request, I have applied a few more
patches which really should be entered into the -rc:s. As it appears
that you have not yet pulled v1, I figured sending a v2 in its place
would be appropriate, so here it is.

This almost looks good, I just have one comment:

Unless I'm missing something here, this one is not really rcN material, so
I'd appreciate if you could queue it to your for-mfd branch instead.

The rest is pulled and applied, thanks again.

The last two:

  mfd: ab8500-sysctrl: Set sysctrl_dev during probe
  mfd: ab8500-sysctrl: Let sysctrl driver work without pdata

are actually fixes for bugs introduced in this merge window that
inhibited the ab8500-sysctl driver as a consequence.  Would you
reconsider pulling just those?

Thanks,

A good way to make sure that patches fixing regressions are applied
to the -rc series is to indicate in the commit message or even the
heading that it fixes a regression.

I usually try to begin such commits with the text:

  this patch fixes a regression caused by change 018745435
  "foo: fix bar"...

Then copying in some crash dump text never hurts :-)

It makes it very easy for us as subsystem maintainers to pick
regression fixes.

Right, I actually pointed to the culprit commit (applied during the
merge window) in the message, but I'll try to be more direct next time.
I also agree on the crash dump, but unfortunately this one was failing
silently. :-)

Thanks for the tip!

This one is already in mfd-fixes, the commit log was clear enough.

This one is not, as the commit log is not showing it actually fixes something
but only makes the code cleaner. If it really fixes something, could you
please provide me with a commit log that describes what exactly it fixes ?

Ok, the fix here is that right now that driver is initialized without a
specific pdata (that is plat->sysctrl), so enforcing it breaks existing
platforms for no reason.  To make the commit more clear I would just
point that out as in (just last two sentences):

--- >8 ---
mfd: ab8500-sysctrl: Let sysctrl driver work without pdata

A check for a valid plat->sysctrl was introduced in:

2377e52 mfd: ab8500-sysctrl: Error check clean up

but the driver works just fine even without that initialization data,
and enforcing it breaks existing platforms for no reason.

This patch removes the check and let the driver go ahead with probe.
--- >8 ---

Is it better?

Thanks,
Fabio

Great!

Ok, the fix here is that right now that driver is initialized without a
specific pdata (that is plat->sysctrl), so enforcing it breaks existing
platforms for no reason.  To make the commit more clear I would just
point that out as in (just last two sentences):

--- >8 ---
mfd: ab8500-sysctrl: Let sysctrl driver work without pdata

A check for a valid plat->sysctrl was introduced in:

2377e52 mfd: ab8500-sysctrl: Error check clean up

but the driver works just fine even without that initialization data,
and enforcing it breaks existing platforms for no reason.

This patch removes the check and let the driver go ahead with probe.
--- >8 ---

Is it better?

Thanks,
Fabio

Slightly. Next time please describe how it breaks.
I applied and pushed this patch now, I'll send a pull request to Linus
