[PATCH v4 4/9] staging: media: atomisp: use __func__ over function names

[Deepak R Varma]

Replace hard coded function names from the debug print strings by
standard __func__ predefined identifier. This resolves following
checkpatch script WARNING:
Prefer using '"%s...", __func__' to using function's name, in a string.

[PATCH v4 6/9] staging: media: atomisp: fix CamelCase variable naming

[Deepak R Varma]

Mixed case variable names are discouraged and they result in checkpatch
script "Avoid CamelCase" warnings. Replace such CamelCase variable names
by lower case strings according to the coding style guidelines.

[PATCH v4 7/9] staging: media: atomisp: replace raw pr_*() by dev_dbg()

[Deepak R Varma]

It is recommended to use driver model diagnostic macros dev_*() instead
of raw printk() or pr_*() since the former ensures that the log messages
are always associated with the corresponding device and driver. This also
addresses the checkpatch complain for not using KERN_<LEVEL> facility in
printk() call.

Suggested-by: Fabio Aiuto <fabioaiuto83@gmail.com>
Signed-off-by: Deepak R Varma <drv@mailo.com>

Changes since v3:
   - use dev_dbg instead of dev_info since it spams less
Changes since v2:
   - Tag Fabio Auito for the patch suggestion
Changes in v1:
   - implement following changes suggested by Fabio Aiuto
       a. use dev_info instead of pr_info
       b. update patch log message accordingly

oops... sorry for the oversight. Not sure how I missed it.
I will wait for any other feedback on other patches and send
in a corrected version shortly.

I've fixed this up myself.

I'm taking this series and make a PR for this, wrapping up these
atomisp cleanups.

If you plan any more cleanups, then please do this on top of this
branch: https://git.linuxtv.org/hverkuil/media_tree.git/log/?h=for-v5.14-out1

That contains all pending cleanups for staging/media.

Regards,

	Hans

Thank you Hans and everyone. Appreciate your time, comments and patience. I
understand this entire patch series is acceptable for your consideration and
that I can now move on to other changes.

I will be sending additional clean up patches and I will base those on top of the
mentioned branch.

Have a good one.
deepak.

Hello Hans,
I have cloned media_tree repository and checked out branch for-v5.14-out1

Is it okay for me to start my next patch in this branch? I do not need for
you the last patch set to be applied to the git tree, correct?

Thank you,
deepak.

Huh? Why are you sending a new version when there's no difference
from the past ones?

As Dan already pointed, please delete this and other
dev_dbg() that are just tracing functions without any other
real meaning. If one needs that, ftrace could be used.

This one for instance, is not a plain trace, so it could make
sense to be kept, but please remove those "+++..."  sequences
from the string, as this has no meaning. So, just:

 	dev_dbg(&client->dev,
		"%s: coarse_itg %d, gain %d, digitgain %d\n",
		__func__, coarse_itg, gain, digitgain);

would be enough.

There's a typo here:

Please fix.

Btw, the entire logic above could be re-written as:

	dev_dbg(&client->dev, "%s: %s\n", __func__,
		enable ? "on" : "off");

Sorry, I thought I have to resend the whole patch set so that all the
patches have the same version history. Are you saying I just resend the
ones that required a change? No need to include those that do not have any
comments / feedback or are acked?

I have made this correction in a separate patch send afterwards. I will
confirm if this file was included. If not, I will include this in the next
version.
