[PATCH 0/5] ASoC: fix error-path leaks and a NULL dereference

[shao.mingyin at zte.com.cn]

Five error-path defects in ASoC drivers, found while reviewing against
linux-next next-20261030.  Four of them leak a reference or a clock, or
drop one twice, on a path that is easy to miss; the fifth dereferences
a NULL remote port while parsing an audio graph.  The patches are
independent and can be reviewed, applied and backported separately.

  1/5 ASoC: rsnd: fix NULL dereference when remote port has no endpoint
  2/5 ASoC: wcd9335: fix SLIM interface device double-put on error paths
  3/5 ASoC: rockchip: rk3399_gru_sound: fix codec node reference leak
  4/5 ASoC: sun8i-codec: fix bus clock leak in runtime resume error path
  5/5 ASoC: rsnd: fix SSIU node reference leak in rsnd_dma_of_path

1/5 returns early when a graph endpoint has no remote port; 2/5 removes
the four manual put_device() calls that duplicate the devm action; 3/5
puts the codec node on the two skip paths of the Rockchip DAI-link
parse; 4/5 disables the bus clock when the regmap sync fails; 5/5 puts
the SSIU node after the DMA path lookup.

Patches 1/5 and 5/5 are R-Car (Kuninori Morimoto), 2/5 is the WCD9335
codec (Srinivas Kandagatla), 3/5 is Rockchip (Heiko Stuebner) and 4/5
is sunxi (Chen-Yu Tsai, Jernej Skrabec, Samuel Holland).  All go
through the ASoC tree.

3/5 was tested on 7.3.0-next-20261030 in a QEMU/TCG arm64 guest with a
synthetic DT; the test section in that patch describes the setup and
the observed reference counts.
