Subject: [PATCH net-next v3 25/31] wan: cosa: remove dead cosa_net_ioctl() function
Date: Tue, 27 Jul 2021 15:45:11 +0200 [thread overview]
Message-ID: <20210727134517.1384504-26-arnd@kernel.org> (raw)
In-Reply-To: <20210727134517.1384504-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
The ndo_do_ioctl callback is never called with the COSAIO* commands,
so this is never used. Call the hdlc_ioctl function directly instead.
Any user space code that relied on this function working as intended
has never worked in a mainline kernel since before linux-1.0.
