Fix the pointer-integer size mismatch warnings below:

	drivers/staging/bcm/CmHost.c:1387:39: warning: cast to pointer from
			integer of different size [-Wint-to-pointer-cast]
	  pstAddIndication->psfAuthorizedSet = (struct bcm_connect_mgr_params *)ntohl((ULONG)pstAddIndication->psfAuthorizedSet);
					       ^
	drivers/staging/bcm/CmHost.c:1426:37: warning: cast to pointer from
			integer of different size [-Wint-to-pointer-cast]
	  pstAddIndication->psfAdmittedSet = (struct bcm_connect_mgr_params *)ntohl((ULONG)pstAddIndication->psfAdmittedSet);
					     ^
	drivers/staging/bcm/CmHost.c:1440:35: warning: cast to pointer from
			integer of different size [-Wint-to-pointer-cast]
	  pstAddIndication->psfActiveSet = (struct bcm_connect_mgr_params *)ntohl((ULONG)pstAddIndication->psfActiveSet);

No.  You haven't fixed the bug, you've just silenced the warning so now
someone has to spent hours and hours looking for it when it comes time
to write a proper fix.  Don't do that.

I had thought silencing warning may be better in someway for some people.
But, anyway, now I agree and respect your opinion. Thank you for the opinion :)

Don't worry about it.  You're not the first person to try submit that
patch.

When I last looked at it, this driver only worked under 32 bits and
there were other 64 bit bugs as well besides this one.

Thank you very much for your kind reply. I'm yet newbie to kernel community
and thinking I should try with unavoidable mistakes. Your reply have gave me
more courage for trial.
I will not forget the learning I got from this trial :)
