Subject: [PATCH net-next v3 21/31] hippi: use ndo_siocdevprivate
Date: Tue, 27 Jul 2021 15:45:07 +0200	[thread overview]
Message-ID: <20210727134517.1384504-22-arnd@kernel.org> (raw)
In-Reply-To: <20210727134517.1384504-1-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.
