[PATCH v2 0/4] Enable USB serial console on the D-Link DNS-313

[Linus Walleij]

This patch set makes it possible to plug in a USB cable
into the device USB B receptacle on the DNS-313 and
it will appear as /dev/ttyACM0 on the host and there will
be a serial console on it, at 115200 baud.

This is useful for users who don't like to solder in
their device to get a serial console.

I did some minor patching to the usbgadet utility package
to make things work properly for me.

The custom inittab is a bit ugly, but I've seen that this
seems to be what other devices do, other ideas welcome.
