From: Ben Hutchings <bhutchings@...arflare.com>
To: David Miller <davem@...emloft.net>
Cc: netdev@...r.kernel.org, linux-net-drivers@...arflare.com
Subject: [PATCH 3/3] netdev: Convert MDIO ioctl implementation to use
struct mii_ioctl_data
A few drivers still access the arguments to MDIO ioctls as an array of
u16. Convert them to use struct mii_ioctl_data.
Signed-off-by: Ben Hutchings <bhutchings@...arflare.com>
---
The PCMCIA drivers are compile-tested. The emac driver is not since
it's for PPC only, but I'm fairly confident that it will work.
Ben.
