Subject: [PATCH v2 11/20] EDAC, ghes: Remove intermediate buffer pvt->detail_location
Date: Wed, 6 Nov 2019 09:33:25 +0000 [thread overview]
Message-ID: <20191106093239.25517-12-rrichter@marvell.com> (raw)
In-Reply-To: <20191106093239.25517-1-rrichter@marvell.com>
detail_location[] is used to collect two location strings so they can
be passed as one to trace_mc_event(). Instead of having an extra copy
step, assemble the location string in other_detail[] from the
beginning.
Using other_detail[] to call trace_mc_event() is now the same as in
edac_mc.c and code can be unified.
