Subject: [PATCH v2 17/20] EDAC, mc: Rework edac_raw_mc_handle_error() to use struct dimm_info
Date: Wed, 6 Nov 2019 09:33:39 +0000 [thread overview]
Message-ID: <20191106093239.25517-18-rrichter@marvell.com> (raw)
In-Reply-To: <20191106093239.25517-1-rrichter@marvell.com>
The error handling functions have the pos[] array argument for
determing the dimm handle. Rework those functions to use the dimm
handle directly.
