[Greg Kroah-Hartman]

From: Vasily Averin <vvs@xxxxxxxxxx>

[ Upstream commit dccd855771b37820b6d976a99729c88259549f85 ]

Fixes sparce warnings:
fs/notify/fanotify/fanotify_user.c:267:63: sparse:
 warning: restricted fmode_t degrades to integer
fs/notify/fanotify/fanotify_user.c:1351:28: sparse:
 warning: restricted fmode_t degrades to integer

FMODE_NONTIFY have bitwise fmode_t type and requires __force attribute
for any casts.
