Pablo Neira Ayuso a31f2d17b3 netlink: add netlink_kernel_cfg parameter to netlink_kernel_create
This patch adds the following structure:

struct netlink_kernel_cfg {
        unsigned int    groups;
        void            (*input)(struct sk_buff *skb);
        struct mutex    *cb_mutex;
};

That can be passed to netlink_kernel_create to set optional configurations
for netlink kernel sockets.

I've populated this structure by looking for NULL and zero parameters at the
existing code. The remaining parameters that always need to be set are still
left in the original interface.

That includes optional parameters for the netlink socket creation. This allows
easy extensibility of this interface in the future.

This patch also adapts all callers to use this new interface.

David S. Miller b26d344c6b Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts:
	drivers/net/caif/caif_hsi.c
	drivers/net/usb/qmi_wwan.c

The qmi_wwan merge was trivial.

The caif_hsi.c, on the other hand, was not.  It's a conflict between
1c385f1fdf ("caif-hsi: Replace platform
device with ops structure.") in the net-next tree and commit
39abbaef19 ("caif-hsi: Postpone init of
HIS until open()") in the net tree.

I did my best with that one and will ask Sjur to check it out.

Ben Chan 9f77186dd1 staging: gdm72xx: Release netlink socket properly
This patch modifies the gdm72xx driver to properly release a netlink
socket using netlink_kernel_release. It fixes the following kernel
crash, which occurs after repeatedly suspending and resuming a system.

Paul Stewart 54bc1ff1da staging: gdm72xx: Set up parent link in sysfs for gdm72xx devices
This patch uses SET_NETDEV_DEV to set up a 'device' parent link in sysfs
(e.g. /sys/class/net/wm0/device) for a gdm72xx device.

Geert Uytterhoeven dd4f521399 staging: gdm72xx: WIMAX_GDM72XX_USB_PM should depend on USB_SUSPEND
Use Kconfig logic instead of a rude #error in the driver source,
which breaks m68k-allmodconfig.
Also remove the "default n", as that's the default.
