[PATCH 0/6] asus-wmi: cleanup dgpu_disable, egpu_enable, panel_od

[Luke D. Jones]

This patch series does two things for previously added features:
- dgpu_disable
- egpu_enable
- panel_od

The fixes add missing documentation, and the refactors vastly clean up how
the features work, including reading the values from WMI methods on *_show()
and checking the result correctly (these methods return 1 on success).

[PATCH 4/6] asus-wmi: Refactor disable_gpu attribute

[Luke D. Jones]

The settings for these attributes can be read from the device, this
is now done instead of reading a stored value from module. The stored
value is also removed.

This means the simpler asus_wmi_dev_is_present() can be used in
*_check_present() - it is not an error for these methods to be
missing.

The _write() functions have their bodies shifted in to *_store()
which simplifies things further.

Thanks for the patch. Note that the Fixes tag should be above your
signed-off-by and then the patch should otherwise have a normal
subject + body. I've changed the commit msg to the following
while merging this:

While merging this I noticed that this is also using spaces
instead of tabs for indentation, where as the rest of
the file is using tabs.

I've also fixed this up while merging, but next time
please make sure to use spaces.

I will make similar spaces -> tabs changes to patch 2/6 and 3/6

Thank you for your patch-series, I've applied the series to my
review-hans branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.

Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.

Regards,

Hans

Ah thank you, sorry about that, I thought I got it correct Perhaps I
didn't read
https://www.kernel.org/doc/html/v4.17/process/submitting-patches.html#describe-changes
well enough.

I ran these through ./scripts/checkpatch.pl... I'm really not sure what
happened. I'll triple-check that in future.
