When building MHI as a module, missing MODULE_LICENSE() warnings
are seen. Avoid them by adding the license and description
information for the files where the warnings are seen.

I would expect you only need to add the MODULE_* once per module, in 
which case main.c is probably the only place that needs it.

Hi Jeff,

I thought so too. This is to fix below warnings seen when building MHI 
as a MODULE:

WARNING: modpost: missing MODULE_LICENSE() in 
drivers/bus/mhi/core/main.o
WARNING: modpost: missing MODULE_LICENSE() in drivers/bus/mhi/core/pm.o
WARNING: modpost: missing MODULE_LICENSE() in 
drivers/bus/mhi/core/boot.o

We've only had those in init.c so far.

Thanks,
Bhaumik

Can you please test below diff to see if it fixes the warning?

Hi Mani,

Yes I was just about to reply. I realized it was due to the Makefile 
change. I have fixed and
tested it. The warnings are gone now. I will remove the patch.

Thanks,
Bhaumik

Where is the patch fixing this issue? I couldn't find it in my inbox.
I'll just post one as I need to send out the PR today.
