Instead of holding a reference to the class device, embed it the
platform_profile_handler. This involves manually creating and
registering the device and replacing dev_get_drvdata() with the newly
created to_pprof_handler() macro.

Add *drvdata to platform_profile_register() signature and assign it to
the class device.
While at it, pass specific driver state as drvdata to replace uses of
container_of() with dev_get_drvdata().

Replace platform_profile_register() with it's device managed version.
Also replace pr_err with dev_err in case of error and make the error

In order to protect the platform_profile_handler from API consumers,
allocate it in platform_profile_register() and modify it's signature
accordingly.
Remove the platform_profile_handler from all consumer drivers and
replace them with a pointer to the class device, which is
now returned from platform_profile_register().
Replace *pprof with a pointer to the class device in the rest of
exported symbols.

Remove parent device *dev from platform_profile_handler, as it's no
longer accessed directly. Rename class_dev -> dev.

Hi all,
I was hoping to finish this in this cycle since it has been so close and
has only required minor tweaks recently.
I went to review the changes once again and ended up applying this now
into the review-ilpo-next branch. Thank you all who worked on to improve
this series! :-)
There were minor nits, however, I hadto address while applying. I added
the justification into 5/19 commit message and changed a few trivial
things in the code. Please check that the diff compared with your series
w/o any modifications makes sense:

For the series up to v4 commit 15/19:
Reviewed-by: Mark Pearson <mpearson-lenovo@squebb.ca>
I need to go over the last few commits just once more, as there a few pieces I need to get my head around - and I'm not going to get it done this evening. Hope it's OK to add review for the bits that I have done.
Thanks
Mark

I, for the first time ever, tested filter-branch and after some initial
hickups on how to specify the commit range, got your Reviewed-bys added
with single command :-).
While at it, I also managed to catch one rev-by line without any
name+email (I assume it was b4 messing something up).
I'll soon want to merge fixes branch into for-next though, and after that
adding any rev-bys will not be as easy as it was now.

Awesome! I believe commit 15/19
a213108c01e0 ("ACPI: platform_profile: Remove platform_profile_handler from exported symbols")
is still missing a rev-by by Mark, if there is still time.

Thanks for noticing this. I just recalled the patch numbering wrong.
It should be fixed now.
