Subject: [media] em28xx: restore lost #ifdef
Author:  Arnd Bergmann <[email protected]>
Date:    Fri Feb 26 08:53:22 2016 -0300

The cleanup that changed the em28xx driver to use v4l2_mc_create_media_graph
instead of its own implementation causes a build error when 
CONFIG_MEDIA_CONTROLLER
is disabled:

drivers/media/usb/em28xx/em28xx-video.c: In function 'em28xx_v4l2_init':
drivers/media/usb/em28xx/em28xx-video.c:2717:38: error: 'struct em28xx' has no 
member named 'media_dev'

This puts the new code inside the same #ifdef that controls the presence
of the 'media_dev' member, and that the old code was in.

Fixes: de39078779cb ("[media] em2xx: use v4l2_mc_create_media_graph()")
