Subject: [RFC net-next 25/28] hippi: use ndo_siocdevprivate
Date: Fri, 6 Nov 2020 23:17:40 +0100 [thread overview]
Message-ID: <20201106221743.3271965-26-arnd@kernel.org> (raw)
In-Reply-To: <20201106221743.3271965-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
The rr_ioctl uses private ioctl commands that correctly pass
all data through ifr_data, which works fine in compat mode.
Change it to use ndo_siocdevprivate as a cleanup.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
