[PATCH] creds: suppress warning in get_cred

From: Stephen Rothwell
Date: Mon Jan 19 2009 - 05:10:45 EST


This is the usual way to force a conversion from a const pointer to a
non-const one and gets rid of this warning:

include/linux/cred.h: In function 'get_cred':
include/linux/cred.h:188: warning: passing argument 1 of 'get_new_cred' discards qualifiers from pointer target type
