    Subject[PATCH AUTOSEL 5.2 063/185] media: fdp1: Reduce FCP not found message level to debug
    Date
    From: Geert Uytterhoeven <geert+renesas@glider.be>

    [ Upstream commit 4fd22938569c14f6092c05880ca387409d78355f ]

    When support for the IPMMU is not enabled, the FDP driver may be
    probe-deferred multiple times, causing several messages to be printed
    like:

    rcar_fdp1 fe940000.fdp1: FCP not found (-517)
    rcar_fdp1 fe944000.fdp1: FCP not found (-517)

    Fix this by reducing the message level to debug level, as is done in the
    VSP1 driver.

    Fixes: 4710b752e029f3f8 ("[media] v4l: Add Renesas R-Car FDP1 Driver")
