Subject: [PATCH net-next v2 19/31] airo: use ndo_siocdevprivate
Date: Tue, 20 Jul 2021 16:46:26 +0200	[thread overview]
Message-ID: <20210720144638.2859828-20-arnd@kernel.org> (raw)
In-Reply-To: <20210720144638.2859828-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

The airo driver overloads SIOCDEVPRIVATE ioctls with another
set based on SIOCIWFIRSTPRIV. Only the first ones actually
work (also in compat mode) as the others do not get passed
down any more.

Change it over to ndo_siocdevprivate for clarification.
