Subject[PATCH 4.1 195/267] md: fix a build warning
Date
4.1-stable review patch.  If anyone has any objections, please let me know.

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

From: Firo Yang <firogm@gmail.com>

commit 4e023612325a9034a542bfab79f78b1fe5ebb841 upstream.

Warning like this:

drivers/md/md.c: In function "update_array_info":
drivers/md/md.c:6394:26: warning: logical not is only applied
to the left hand side of comparison [-Wlogical-not-parentheses]
!mddev->persistent != info->not_persistent||

Fix it as Neil Brown said:
mddev->persistent != !info->not_persistent ||
