Subject[PATCH v2 3/3] lib/vsprintf: Force type of flags value for gfp_t
Date
Sparse is not happy about restricted type being assigned:
lib/vsprintf.c:1940:23: warning: incorrect type in assignment (different base types)
lib/vsprintf.c:1940:23: expected unsigned long [assigned] flags
lib/vsprintf.c:1940:23: got restricted gfp_t [usertype]

Force type of flags value to make sparse happy.
