The patch

   regulator: core: Add label to collate of_node_put() statements

has been applied to the regulator tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-5.4

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.

Thanks,
Mark

Subject: [PATCH] regulator: core: Add label to collate of_node_put()
 statements

In function of_get_child_regulator(), the loop for_each_child_of_node()
contains two mid-loop return statements, each preceded by a statement
putting child. In order to reduce this repetition, create a new label,
err_node_put, that puts child and then returns the required value;
edit the mid-loop return blocks to instead go to this new label.
