Subject: [PATCH 3/3] [media] v4l2-mc: remove unused dtv_demod variable

A recent patch removed the only user of the 'dtv_demod' variable
in v4l2_mc_create_media_graph, but did not remove the declaration,
possibly as a result of an incorrect rebase:

drivers/media/v4l2-core/v4l2-mc.c: In function 'v4l2_mc_create_media_graph':
drivers/media/v4l2-core/v4l2-mc.c:37:55: error: unused variable 'dtv_demod' [-Werror=unused-variable]

This removes the unused variable as well.

Signed-off-by: Arnd Bergmann <arnd@...db.de>
Fixes: 840f5b0572ea ("media: au0828 disable tuner to demod link in au0828_media_device_register()")
