Subject: [PATCH 4.14 26/54] scsi: megaraid_sas: use adapter_type for all gen controllers
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shivasharan S <shivasharan.srikanteshwara@...adcom.com>
commit c365178f3147f38d26c15bdf43a363bacb5406ec upstream.
No functional change.
Refactor adapter_type to set for all generation controllers, not
just for fusion controllers.
