include/linux/cred.h: work around gcc-4.2.4 warning in get_cred()
With gcc 4.2.4 (building UML) I get the warning
include/linux/cred.h: In function 'get_cred':
include/linux/cred.h:189: warning: passing argument 1 of
'get_new_cred' discards qualifiers from pointer target type
Inserting an additional local variable appears to keep the compiler happy,
although it's not clear to me why this should be needed.
