From 02b01e010afeeb49328d35650d70721d2ca3fd59 Mon Sep 17 00:00:00 2001 From: Sumant Patro Date: Wed, 14 Feb 2007 13:00:55 -0800 Subject: [PATCH] [SCSI] megaraid_sas: return sync cache call with success FW does not support SYNCHRONIZE_CACHE cmd. FW flush cache on its own. So, we just return success from the megasas_queue_command.
