[PATCH 0/4] cpufreq: fixes for v3.12

[Sudeep KarkadaNagesha]

From: Sudeep KarkadaNagesha <sudeep.karkadanagesha@arm.com>

Hi Shawn, Guennadi,

These are the fixes for the issue reported by Guennadi.
cpu_dev should point to cpu0 device instead of cpufreq-cpu0 platform
devices. The dev_id is also updated while registering the cpu clocks.

Can you review these ? Tested-by is much appreciated as I don't
have hardware to check the fix.

Regards,
Sudeep

[PATCH 1/4] cpufreq: cpufreq-cpu0: assign cpu_dev correctly to cpu0 device

[Sudeep KarkadaNagesha]

From: Sudeep KarkadaNagesha <sudeep.karkadanagesha@arm.com>

Commit f837a9b5ab05c52a07108c6f09ca66f2e0aee757 "cpufreq: cpufreq-cpu0:
remove device tree parsing for cpu nodes" assumed the pdev->dev is set to
cpu0 device in the platform code. But it actually points to the virtual
cpufreq-cpu0 platform device which is not present in the device tree.
Most of the information needed by cpufreq is stored in cpu0 DT node.
So cpu_dev must point to cpu0 device.

This patch fixes the wrong assignment to cpu_dev.

Noone else seems to complain, but I don't think these =20, =09 etc. codes 
have been invented on my side and I don't think they belong here. I'm 
handling enough mails / patches daily to believe, that my mail system 
isn't the cause of this. Could you please verify and regenerate and 
resend? Unless I'm mistaken this looks like a corruption on your SMTP 
side.

Thanks

Its on Sudeep's side :) .. Or on ARM's side..
Don't know why nobody else complained, Atleast people who test these
patches (Like Shawn), must have applied them from mail.. Don't know
why they aren't shouting :)

He mostly send pull requests to Rafael and so this wasn't a issue for
Rafael :)

Yes looks like its at my end. I will try to fix it. There is alternate
SMTP which should not have this issue, but it was down recently. I
forgot to switch back to it once it was fixed.

For now you can fetch it from:

I'm not sure what's going on here.  But I did apply the patches from
mail without any problem, and the patch I got look just like what the
archive below [1] shows.

This looks like broken quoted-printable e-mail encoding somewhere (either
on the sending or on the receiving end).

Git pulls are, well, from git, so e-mail encoding doesn't have anything to do
with them ...

Hi,

I have a little problem with this series, because the last patch is based
on the current Linus' tree rather than on my master branch which is what
I have ready to push.  I don't think it makes sense to rebase it, however,
because that would introduce a merge conflict for Linus unnecessarily.

To avoid merging stuff back and forth, I'll push this series later in the
cycle.

Thanks,
Rafael

Thanks Rafael.
Let me know in case if you need me to rebase onto your branch.
