------------------
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 ||
