Subject: [PATCH 04/10] staging: ks7010: remove unused ioctl handler
Date:   Mon,  9 Oct 2023 16:19:02 +0200
Message-Id: <20231009141908.1767241-4-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

The ndo_do_ioctl function has no actual callers, and doesn't do much here,
so just remove it entirely as preparation for removing the callback pointer
from net_device_ops.
