[PATCH] drm/arc: make arcpgu_debugfs_init return 0

[Wambui Karuga]

As drm_debugfs_create_files should return void, remove its use as the
return value of arcpgu_debugfs_init and have the latter function
return 0 directly.

Thanks for your patch! I had to go into the ML and find out the series where this
patch belongs to and seen that you have already received some feedback, but I think
a summary is worth:

- you should look if it is possible to make .debugfs_init hook return void, it would
  simplify the cleanup in the drivers by not having to return 0.
- you should put in each driver patch a note that drm_debugfs_create_files() always
  returns 0 since 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail)
  so that people don't have to hunt in the git history for clues.
- Make all the changes into a series

With that, you can have my Acked-by: Liviu Dudau <liviu.dudau@arm.com>

Best regards,
Liviu

I'd split this up a bit differently, with a patch per function. But then
including in that patch the prototype change (at least for the
drm-internal ones that aren't used by drivers). This way reviewers don't
have to check the entire series to make sure that we drop the now
pointeless return value from the implementation of these functions.

I guess you could also just squash this function into the last one, it's a
fairly small patch still.

Re: [PATCH] drm/etnaviv: remove check for return value of drm_debugfs function

And here is where the commit message skips a very important
information: Since 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail) this function never returns
anything other than 0, so there is no point in checking. This
information should be in the commit message, so the reviewer doesn't
need to look up this fact in the git history.

Lucas

[PATCH] drm/v3d: make v3d_debugfs_init return 0

[Wambui Karuga]

As drm_debugfs_create_files should return void, remove its use as the
return value of v3d_debugfs_init and have the function return 0
directly.

[Wambui Karuga]

As drm_debug_create_files will be converted to return void,
drop return value from various drm_debugfs functions that return
drm_debug_create_files and convert the functions to return void.

What order does all of these patches apply in?

You have two of them numbered, but not all, so this is really confusing
as to how to review this...

Can you fix all that up and resend?

For cases like these I think we should go a step further and also
remove the return value from the driver wrapper. And that all the way
up until there's something that actually needs to return a value for
some other reason than debugfs.
