From mboxrd@z Thu Jan 1 00:00:00 1970 From: Brian Norris Subject: [PATCH] mtd: ofpart: drop undocumented, nonfunctional 'lock' property Date: Mon, 26 Oct 2015 18:56:06 -0700 Message-ID: <1445910966-11415-1-git-send-email-computersforpeace@gmail.com> Return-path: Sender: devicetree-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-mtd-IAPFreCvJWM7uuMidbF8XUB+6BGkLq7r@public.gmane.org Cc: devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Brian Norris , Michal Suchanek List-Id: devicetree@vger.kernel.org The 'lock' property of a partition does nothing, because it effectively only sets the flags for the partition device, not the master device. And no MTD driver checks for MTD_POWERUP_LOCK in the partition device, only the master device. Michal noticed that this flag was undocumented, but rather than document a non-functioning DT property, let's just kill it, since obviously no one cared about it. Note that this logic does not apply to all MTD flags (e.g., the "read-only" flags above the "lock" one), since certain flags *do* get checked in the partition, at least in some cases (particularly, when checking file permissions in mtdchar.c, but notably *not* in the core APIs like mtd_write()).
