Fix the following W=1 kernel warnings:

prototype for Function(). Prototype was for rtl8188e_PHY_SetRFReg()
instead.

drivers/staging/r8188eu/hal/rtl8188e_phycfg.c:257: warning: expecting
prototype for Function(). Prototype was for rtl8188e_PHY_QueryRFReg()
instead.

Please put build warning lines all on one line.

No, gcc reported this, not a robot, right?

You have read Documentation/process/researcher-guidelines.rst for how to
properly document patches that are created by research tools like this,
right?  Please fix this commit up to follow those requirements please.

thanks,

Hi Greg and Jiapeng,

First, IMO this is not research tool (in the sense of academic purposes),
but development bot used in corporate environment, kinda like kernel
test robot <lkp@intel.com>. When the bot reports any build warnings,
these will be followed up by developers proposing fixes.

What I see in the patch message is just "Fix this warning..." without
saying why there is the warning.

Second, gcc DOESN'T, again DOESN'T, report "expecting prototype"
warnings. These are from scripts/kernel-doc, which enabled these
warnings on W=1 build.

So the underlying problem is mismatching function name in kernel-doc
comment and actual function.

Thanks.

Ok, then please document it as such and point to where we can find out
more information about it.

Which isn't ok.

Yes, the kernel build reports this, not a random "robot".

Agreed, so the changelog should say as such.
