[PATCH] Staging: board: Fixed the error for implicit declaration of function

[PATCH] Staging: board: Fixed the error for implicit declaration of function

[Shivani Bhardwaj]

Fixed the error for implicit declaration of the function
'of_find_all_nodes' by adding the appropriate header file and declaring
the function before it has been called.

I haven't looked at the code, but I wonder why you need both the header
file and the local declaration?

I tried declaring it first, it didn't work. I added the header, it worked. 
Now, when I tried again, it works without header too. I'll update the 
patch, I must have done something wrong while declaring for the first time. 
Thanks, Julia. I'm sorry I'm making such petty errors, I'm noting 
everything, I'll make sure to send a good patch soon.

If the header declares the function, then it doesn't seem like a good idea
to declare the function locally as well.

Hi Julia! I have a doubt. I think I'm having trouble with the header file 
because it declares the function prototype with an extern keyword (I'm not 
sure if memory allocation plays a role in this). And, if the function has 
been declared in some header file then re-declaration of it won't be a good 
practice, I suppose. Please tell me whether extern has to do anything with 
it or not. This is the header file 
http://lxr.free-electrons.com/source/include/linux/of.h#L189. 
Thank you.

We all have done mistakes while starting. Let me point out one more thing -
please do not top post.

I am not seeing this build error/warning. How you are building it? Can
you please post your .config file.

Why did you suggest to add an include of prom.h rather than of of.h?

You shouldn't declare such a generic function in the specific driver.

Julia, I'm sorry. I looked for all the places where the function was 
available, prom.h wasn't the ideal place though. I've removed it and I'm 
still not able to configure what is causing problems if I do have correct 
header files and everything needed. I'm working on this. Thank you so much.

Hi Sudeep! I'm having trouble with inline mode of communication, I think 
I'm doing it wrong. I'm not getting exactly difference between top-post and 
inline way, I've been warned about this before as well. I'll learn as soon 
as possible. I've sent my .config file. You can check it. 
Thanks a lot!

Ok, now I understand why you are getting the warning. :)
In your .config CONFIG_STAGING_BOARD is not selected. So staging/board
is not included in the build and as a result the modules on which board
is dependent are also not built. So in this scenario when you try to do
make M=drivers/staging/board it gives warning. To test properly try with
make allmodconfig.

Thanks, Sudip! And for last two messages I did make use of mutt, I don't 
know why doesn't it show up.
And, does this mean that every time I compile, I must use allmodconfig?
Thank you

You have top posted again.  Once you make allmodconfig, it should be good
enough to leave it as is, at least until you update your kernel and get a
new Kconfig file.

Done. Seems like those folders didn't have much to compile, only one file 
whose dependencies were compiled.

Hi,

You top posted again even after the explanation from Sudip. :(

Please don't do this. Read this:
http://kernelnewbies.org/mailinglistguidelines

And consider the following line:

'Please do not TOP POST. On almost all open source mailing list
top-posting is considered RUDE.'

Thank you.

Before you send a patch, at least check that you have a .o file or the .c
file that is affected by your patch.  You can also compile by saying make
path/to/file.o.  The only risk with that method is that it won't find
missing dependencies between files, if you eg change a function name in
one place but not everywhere that it is used.  But changes inside
functions often don't relate to that.  And with make path/to/file.o you
will see immediately if it is able to compile your file.

Top posting.. :(

It will not recompile if the .o files are already there and .c files
have not been modified. So if you want to recompile all files do make clean
or much better make distclean. make distclean will clean everything even
your .config file also. But usually when I am working or checking patches
for staging I will just do make clean M=drivers/staging , so it will just
clean staging and now when you make again it will compile all files in
staging which are in your .config.
With sparse if you use C=2 then it will recompile even .o files are
there, but with C=1 the default behaviour of not compiling will take
effect.

Usually I will compile the whole folder. Suppose I change something in
unisys and I want to check it, I will do:
make clean M=drivers/staging/unisys
make M=drivers/staging/unisys
