commit 1118020b3b7ab2fbc5806434866867b2ab357f4d
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I60PLB

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=1118020b3b7ab2fbc5806434866867b2ab357f4d

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

commit 58d1c124 upstream.

When a mix of FCP-2 (tape) and non-FCP-2 targets are present, FCP-2 target
state was incorrectly transitioned when both of the targets were gone. Fix
this by ignoring state transition for FCP-2 targets.
