You have a brain, checkpatch is brainless.
Please remember to do more than just shut-up checkpatch.

This could be simplified by removing parentheses and ternaries to

		isShortGI = ht_cap->Ch1Width ? ht_cap->ShortGI40Mhz
					     : ht_cap->ShortGI20Mhz;

[SIMRAN SINGHAL]

Yes, I totally agree with joe.

But as there is no coding style issue in this patch.
So, do I have to resend the complete patch series again?

Style is more than just checkpatch conformity.

I'm not applying any of these so that's entirely up
to Greg.

Perhaps he might apply the first 5 patches and reject
this one, maybe he might apply all the patches.

In any case, do strive to develop some reasonable
semblance of style and do more than just checkpatch
suggested patches and find and fix some actual defect
somewhere.

Joe, I am new to Linux kernel and just have basic knowledge of
 C and C++.
For doing more than checkpatches I need to explore Linux kernel more,
so please suggest me some tasks that help me in exploring
Linux kernel, which helps me in building the better understanding of codes,
which I am finding difficult to understand so that I can do more than
just checkpatch.

Thanks,
Simran

Linux kernel isn't a great project to learn c/c++ as
it is a relatively old, complex project without a lo
of obvious defects.

see: http://kernelnewbies.org

Make sure you read the kernel newbies lists and the
kernel process help files in Documentation/process/.

In the drivers/staging directory tree are many TODO
files.  Read some of them.

List of kernel related bugs to fix:

As Joe said, the kernel is _not_ the project to learn C with.  Please
get some more experience with userspace programs in C first, before
working on the kernel.  It will be much easier for you.

thanks,

[SIMRAN SINGHAL]

I didn't mean what you get. I just want to say I am a beginner and like to
contribute to Linux kernel. But at present, I am in learning mode.

I never mean that I am doing this for learning C or C++ but yes for
contributing to
Linux kernel in every possible way.

And, would be very happy if you guide me so that I can improve.
