You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >>From 842a8824274de3fbbc8e230355d5c75237453bf5 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 12 Jul 2016 11:23:50 +0000 Subject: [PATCH] regulator: act8865: Fix missing of_node_put() in act8865_pdata_from_dt() This node pointer is returned by of_get_child_by_name() with refcount incremented in this function. of_node_put() is missing when exitting this function while invalid device type. Fix it by move of_get_child_by_name() code after device type check. Found by Coccinelle.
