Subject: SCSI: libsas: continue revalidation
From: Dan Williams <[email protected]>
commit 26f2f199ff150d8876b2641c41e60d1c92d2fb81 upstream.
Continue running revalidation until no more broadcast devices are
discovered. Fixes cases where re-discovery completes too early in a
domain with multiple expanders with pending re-discovery events.
Servicing BCNs can get backed up behind error recovery.
