Subject: [PATCH 18/19] EDAC, ghes: Unify trace_mc_event() code with edac_mc driver
Date: Thu, 10 Oct 2019 20:25:40 +0000
Message-ID: <20191010202418.25098-19-rrichter@marvell.com> (raw)
In-Reply-To: <20191010202418.25098-1-rrichter@marvell.com>

The code in ghes_edac.c and edac_mc.c for grain_bits calculation and
calling trace_mc_event() is now the same. Move it to a single location
in edac_raw_mc_handle_error().

The only difference is the missing IS_ENABLED(CONFIG_RAS) switch, but
this is needed for ghes too.
