Hi Liu,

Thanks for the clarification.

I misunderstood your previous comment. I will update the patch to keep
using __free(device_node) in imx8qxp_pxl2dpi_find_next_bridge(),
change imx8qxp_pxl2dpi_get_available_ep_from_port() to return int and
pass the endpoint through an output argument, but avoid adding cleanup
action usage in imx8qxp_pxl2dpi_get_available_ep_from_port() and
imx8qxp_pxl2dpi_set_pixel_link_sel().

I will also drop the unnecessary local NULL initialization for ep,
since the helper initializes the output argument to NULL.

I will send a v6.

Best regards,
Guangshuo
