Subject: sed-opal: ignore locking ranges array when not enabling SUM.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=06564bae93d024e346c49304dfb4e2aaa68cf620;p=thirdparty%2Fkernel%2Flinux.git

sed-opal: ignore locking ranges array when not enabling SUM.

The locking ranges count and the array items are always ignored unless
Single User Mode (SUM) is requested in the activate method.

It is useless to enforce limits of unused array in the non-SUM case.
