[RFC PATCH 3/3] encoder-tpd12s015: keep the ls_oe_gpio on while the phys_addr is valid

From: Hans Verkuil As long as there is a valid physical address in the EDID and the omap CEC support is enabled, then we keep ls_oe_gpio on to ensure the CEC signal is passed through the tpd12s015. Signed-off-by: Hans Verkuil Suggested-by: Tomi
