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||

I fix it by enclosing !mddev->persistent with parentheses

By the way, I also fixed a line over 80 characters warning outputed
by ./scripts/checkpatch.pl
