Subject: [PATCH] lib/scatterlist: Avoid a double memset
Date: Sun, 20 Sep 2020 09:15:44 +0200 [thread overview]
Message-ID: <20200920071544.368841-1-christophe.jaillet@wanadoo.fr> (raw)
'sgl' is zeroed a few lines below in 'sg_init_table()'. There is no need to
clear it twice.
Remove the redundant initialization.
