Subject: [PATCH net-next v3 18/31] hamradio: use ndo_siocdevprivate
Date: Tue, 27 Jul 2021 15:45:04 +0200 [thread overview]
Message-ID: <20210727134517.1384504-19-arnd@kernel.org> (raw)
In-Reply-To: <20210727134517.1384504-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
hamradio uses a set of private ioctls that do seem to work
correctly in compat mode, as they only rely on the ifr_data
pointer.
Move them over to the ndo_siocdevprivate callback as a cleanup.
