Subject: [PATCH v2 05/10] EDAC/mc: Create new function edac_inc_csrow()
Date: Thu, 5 Dec 2019 09:38:06 +0000
Message-ID: <20191205093739.4040-6-rrichter@marvell.com> (raw)
In-Reply-To: <20191205093739.4040-1-rrichter@marvell.com>

Have a separate function to count errors in csrow/channel. This better
separates code and reduces the indentation level. No functional
changes.
