From 95fbadbb5566e383f0cfe40d895e698ab38bdbc7 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 9 Dec 2019 11:09:15 +0000 Subject: fs/adfs: dir: add common dir object initialisation Initialise the dir object before we pass it down to the directory format specific read handler. This allows us to get rid of the initialisation inside those handlers.
