Subject: mm: nommu: fix a compile warning in do_mmap_pgoff()
From: Namhyung Kim <namhyung@xxxxxxxxx>
Because 'ret' is declared as int, not unsigned long, no need to cast the
error contants into unsigned long. If you compile this code on a 64-bit
machine somehow, you'll see following warning:
CC mm/nommu.o
mm/nommu.c: In function `do_mmap_pgoff':
mm/nommu.c:1411: warning: overflow in implicit constant conversion
