[PATCH v2 02/19] scsi: libsas and users: Remove notifier indirection
From: Ahmed S. Darwish
Date: Tue Jan 12 2021 - 06:07:48 EST
From: John Garry <john.garry@xxxxxxxxxx>
The LLDDs report events to libsas with .notify_port_event and
.notify_phy_event callbacks.
These callbacks are fixed and so there is no reason why we cannot call the
functions directly, so do that.
This neatens the code slightly.
[a.darwish@xxxxxxxxxxxxx: Remove the now unused "sas_ha" local variables]
Signed-off-by: John Garry <john.garry@xxxxxxxxxx>
