Subject: [PATCH 10/21] EDAC, ghes: Remove pvt->detail_location string
Date: Wed, 29 May 2019 08:44:26 +0000
Message-ID: <20190529084344.28562-11-rrichter@marvell.com> (raw)
In-Reply-To: <20190529084344.28562-1-rrichter@marvell.com>

The detail_location[] string in struct ghes_edac_pvt is complete
useless and data is just copied around. Put everything into
e->other_detail from the beginning.
