Subject: [efi] Return success from Stop() if driver is already stopped
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ea5762d9d0ebe61bf58f7b8c019bf06c14a693d8;p=thirdparty%2Fipxe.git

[efi] Return success from Stop() if driver is already stopped

Return success if asked to stop driving a device that we are not
currently driving.  This avoids propagating spurious errors to an
external caller of DisconnectController().
