From: "Ewan D. Milne" <emilne@xxxxxxxxxx> If a device does not report a unit attention as expected, clear the expecting_cc_ua flag so that we will not suppress a future unit attention condition that is *not* expected. INQUIRY and REPORT LUNS commands should not do this, however, because they do not report pending unit attention conditions. Signed-off-by: Ewan D.
