V4L/DVB (11380): v4l2-subdev: change s_routing prototype
It is no longer needed to use a struct pointer as argument, since v4l2_subdev doesn't require that ioctl-like approach anymore. Instead just pass the input, output and config (new!) arguments directly. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

=======
So to specify a complete routing scheme for the msp3400 you will have to
- specify in the 'input' field of the v4l2_routing struct:
+ specify in the 'input' arg of the s_routing function:
1) which tuner input to use
2) which SCART input to use
3) which DSP input to use for each DSP output
- And in the 'output' field of the v4l2_routing struct you specify:
+ And in the 'output' arg of the s_routing function you specify:
1) which SCART input to use for each SCART output
