ARM: OMAP: board-4430sdp: Provide regulator to pwm-backlight
The pwm-backlight driver now takes a mandatory regulator that is gotten during driver probe. Initialize a dummy regulator to satisfy this requirement. Signed-off-by: Andrew Chew <achew@nvidia.com> Tested-by: Peter Ujfalusi <peter.ujfalusi@ti.com> [tony@atomide.com: updated fixed regulator id to avoid errors] Signed-off-by: Tony Lindgren <tony@atomide.com>
