V4L/DVB (12530): soc-camera: switch to using v4l2_subdev_call()
Use v4l2_subdev_call() instead of v4l2_device_call_until_err() in all host drivers and in soc-camera core. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>hifive-unleashed-5.1
