Subject: [PATCH v2 08/10] EDAC/mc: Pass the error descriptor to error reporting functions
Date: Thu, 5 Dec 2019 09:38:12 +0000
Message-ID: <20191205093739.4040-9-rrichter@marvell.com> (raw)
In-Reply-To: <20191205093739.4040-1-rrichter@marvell.com>

Most arguments of error reporting functions are already stored in
struct edac_raw_error_desc error descriptor. Pass the error descriptor
to the functions and reduce the functions' arg list.
