Subject: [PATCH] media: i2c: adv748x: Restore full DT paths in kernel messages

As of_node_full_name() now returns only the basename, the endpoint
information printed became useless:

    adv748x 4-0070: Endpoint endpoint on port 7
    adv748x 4-0070: Endpoint endpoint on port 8
    adv748x 4-0070: Endpoint endpoint on port 10
    adv748x 4-0070: Endpoint endpoint on port 11

Restore the old behavior by using "%pOF" instead:

    adv748x 4-0070: Endpoint /soc/i2c@...d8000/video-receiver@...port@...ndpoint on port 7
    adv748x 4-0070: Endpoint /soc/i2c@...d8000/video-receiver@...port@...ndpoint on port 8
    adv748x 4-0070: Endpoint /soc/i2c@...d8000/video-receiver@...port@...endpoint on port 10
    adv748x 4-0070: Endpoint /soc/i2c@...d8000/video-receiver@...port@...endpoint on port 11

Fixes: a7e4cfb0a7ca4773 ("of/fdt: only store the device node basename in full_name")
