unitialized return value in mm/mlock.c: __mlock_vma_pages_range()
Fix an unitialized return value when compiling on parisc (with CONFIG_UNEVICTABLE_LRU=y):
mm/mlock.c: In function `__mlock_vma_pages_range':
mm/mlock.c:165: warning: `ret' might be used uninitialized in this function
Signed-off-by: Helge Deller <deller@gmx.de>
[ It isn't ever really used uninitialized, since no caller should ever
call this function with an empty range. But the compiler is correct
that from a local analysis standpoint that is impossible to see, and
fixing the warning is appropriate. ]
