Subject: [PATCH v2] EDAC/mc: Create new function edac_inc_csrow()
Date: Fri, 14 Feb 2020 15:17:56 +0100	[thread overview]
Message-ID: <20200214141757.8976-1-rrichter@marvell.com> (raw)
In-Reply-To: <20200123090210.26933-6-rrichter@marvell.com>

Have a separate function to count errors in csrow/channel. This better
separates code and reduces the indentation level.

Implementation note: Function edac_inc_csrow() counts the same as
before, ->ce_count is only incremented if row >= 0. This is esp. true
for the case of (!e->enable_per_layer_report). Here, a DIMM was not
found, variable row still has a value of -1 and ->ce_count is not
incremented.

   (!e->enable_per_layer_report),
 * reordered variable declarations
