SubjectApplied "regulator: act8865: Fix missing of_node_put() in act8865_pdata_from_dt()" to the regulator tree
The patch

regulator: act8865: Fix missing of_node_put() in act8865_pdata_from_dt()

has been applied to the regulator tree at


All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

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.

Subject: [PATCH] regulator: act8865: Fix missing of_node_put() in

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.
