gpio reset info is passed to the tfp410 panel driver via the panel's platform data struct 'tfp410_platform_data'. The tfp driver doesn't use the reset_gpio field in the omap4_panda_dvi_device struct. Remove this field. Signed-off-by: Archit Taneja <archit@ti.com> Cc: Tony Lindgren <tony@atomide.com>
