Subject: [PATCH net-next v3 22/31] sb1000: use ndo_siocdevprivate
Date: Tue, 27 Jul 2021 15:45:08 +0200	[thread overview]
Message-ID: <20210727134517.1384504-23-arnd@kernel.org> (raw)
In-Reply-To: <20210727134517.1384504-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

The private sb1000 ioctl commands all work correctly in
compat mode. Change the to ndo_siocdevprivate as a cleanup.
