Subject: [PATCH V2 1/9] pm80xx : redefine sas_identify_frame structure
Date: Wed, 18 Feb 2015 05:06:42 +0530	[thread overview]
Message-ID: <20150217233650.9091-2-Viswas.G@microsemi.com> (raw)
In-Reply-To: <20150217233650.9091-1-Viswas.G@microsemi.com>

sas_identify structure defined by pm80xx doesn't have CRC field.
So added a new sas_identify structure without CRC.

v2:
	- Since the structure changes is applicable for only pm80xx,
	  sas_identify_frame_local structure moved to pm80xx_hwi.h.
