Currently, in omap_vout_isr(), if the panel type is DPI, and if we get either VSYNC or VSYNC2 interrupts, we proceed ahead to set the current buffers state to VIDEOBUF_DONE and prepare to display the next frame in the queue. On OMAP4, because we have 2 LCD managers, the panel type itself is not sufficient to tell if we have received the correct irq, i.e, we shouldn't proceed ahead if we get a VSYNC interrupt for LCD2 manager, or a VSYNC2 interrupt for LCD manager. Fix this by correlating LCD manager to VSYNC interrupt and LCD2 manager to VSYNC2 interrupt. Signed-off-by: Archit Taneja <redacted>
