Since we are processing events synchronously now, the second call of sas_ex_join_wide_port() in sas_ex_discover_dev() is not needed. There will be no races with other works in disco workqueue. So remove the second sas_ex_join_wide_port(). I did not change the return value of 'res' to error when discover failed because we need to continue to discover other phys if one phy discover failed. So let's keep that logic as before and just add a debug log to detect the failure. And directly return if second fanout expander attatched to the parent expander because it has nothing to do after the phy is disabled. Signed-off-by: Jason Yan <yanaijie@xxxxxxxxxx> ---
