[PATCH for-next 2/5] Revert "scsi: hisi_sas: Don't send bcast events from HW during nexus HA reset"

From: Jie Zhan
Date: Fri Nov 18 2022 - 03:38:41 EST


This reverts commit f5f2a2716055ad8c0c4ff83e51d667646c6c5d8a.

This is now unnecessary to solve the SATA devices missing issue in
hisi_sas_clear_nexus_ha(). Hence, we should not ignore bcast events during
sas_eh_handle_sas_errors() in case of missing bcast events, unless a
justified need is found and a mechanism to defer (but not ignore) bcast
events in sas_eh_handle_sas_errors() is provided.

Also, in hisi_sas_clear_nexus_ha(), there is nothing further to handle in
"out: " other than return, so that part can be reverted.
