Subject[PATCH][V2][next] ASoC: rk817: remove redundant assignment to pointer node, add missing of_node_put
From: Colin Ian King <>

The pointer node is being initialized with a value that is never read and
it is being updated later with a new value. The initialization is
redundant and can be removed.

The function is missing a of_node_put on node, fix this by adding the call
before returning.

Addresses-Coverity: ("Unused value")
Fixes: 0d6a04da9b25 ("ASoC: Add Rockchip rk817 audio CODEC support")
Signed-off-by: Colin Ian King <>
V2: Add missing of_node_put call, kudos to Dan Carpenter for spotting this
