From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bhumika Goyal Subject: [PATCH] net: ieee802154: constify ieee802154_ops structures Date: Tue, 22 Nov 2016 02:00:14 +0530 Message-ID: <1479760214-32624-1-git-send-email-bhumirks@gmail.com> Cc: Bhumika Goyal To: julia.lawall@lip6.fr, michael.hennerich@analog.com, aar@pengutronix.de, stefan@osg.samsung.com, linux-wpan@vger.kernel.org, netdev@vger.kernel.org, linux-kernel@vger.kernel.org Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org Declare the structure ieee802154_ops as const as it is only passed as an argument to the function ieee802154_alloc_hw. This argument is of type const struct ieee802154_ops *, so ieee80254_ops structures having this property can be declared as const.
