Subject: [PATCH v2 18/20] EDAC: Store error type in struct edac_raw_error_desc
Date: Wed, 6 Nov 2019 09:33:41 +0000
Message-ID: <20191106093239.25517-19-rrichter@marvell.com> (raw)
In-Reply-To: <20191106093239.25517-1-rrichter@marvell.com>

Store the error type in struct edac_raw_error_desc. This makes the
type parameter of edac_raw_mc_handle_error() obsolete.
