[PATCH AUTOSEL 4.19 047/128] media: fdp1: Reduce FCP not found message level to debug

[Sasha Levin]

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.

[PATCH AUTOSEL 4.19 053/128] media: vsp1: fix memory leak of dl on error return path

[Sasha Levin]

From: Colin Ian King <colin.king@canonical.com>

[ Upstream commit 70c55c1ad1a76e804ee5330e134674f5d2741cb7 ]

Currently when the call vsp1_dl_body_get fails and returns null the
error return path leaks the allocation of dl. Fix this by kfree'ing
dl before returning.

Addresses-Coverity: ("Resource leak")
