This converts users of mdiobus to mdiodev using the following semantic
patch:

@@
identifier mdiodev;
expression regnum;
@@

- mdiobus_read(mdiodev->bus, mdiodev->addr, regnum)
+ mdiodev_read(mdiodev, regnum)

@@
identifier mdiodev;
expression regnum, val;
@@

- mdiobus_write(mdiodev->bus, mdiodev->addr, regnum, val)
+ mdiodev_write(mdiodev, regnum, val)

I am not too experienced with coccinelle, so pointers would be
appreciated. In particular, is it possible to convert things like

bus = mdiodev->bus;
addr = mdiodev->addr;
mdiobus_foo(bus, addr, ...);

in a generic way?
