Subject: [39/89] fat: Fix corrupt inode flags when remove ATTR_SYS flag

2.6.39-stable review patch.  If anyone has any objections, please let us know.

------------------

From: OGAWA Hirofumi <hirofumi@...l.parknet.co.jp>

commit 1adffbae22332bb558c2a29de19d9aca391869f6 upstream.

We are clearly missing '~' in fat_ioctl_set_attributes().
