assert macro to check null

[Saket Sinha <saket.sinha89@xxxxxxxxx>]

I have developed a driver which has become unstable. Now when I debug,I find that it is crashing at 

http://lxr.free-electrons.com/source/kernel/cred.c?v=3.8#L431

get_cred(new); where null is struct cred *new.

 

I think this new might be NULL.

Now I plan to add an assert in our macro that deals with creds, like for asserting passed object isn't NULL.

Any suggestions as to how I can do that?

Regards,

Saket Sinha
