Merge drm/drm-next into drm-intel-next-queued

Some DSI and VBT pending patches from Hans will apply
cleanly and with less ugly conflicts if they are rebuilt
on top of other patches that recently landed on drm-next.

- *
- * For serial (/dev/ttyS0 etc), we can not have hardcoded serial port

- * serial ports, we use dynamic serial port discovery that the serial.c
- * driver uses for pci/pnp ports (there is an entry for the SGI ioc3

- * serial driver adds addresses to get to higher ports).

- * The first one to do a register_console becomes the preferred console
- * (if there is no kernel command line console= directive). /dev/console
- * (ie 5, 1) is then "aliased" into the device number returned by the
