The patch
ASoC: cs35l35: Clear reset_gpio on the error path in probe
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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] ASoC: cs35l35: Clear reset_gpio on the error path in probe
The error path in probe attempts to put the device back into reset.
Should we fail to get the reset_gpio (such as a probe defer) we will
leave the error value in there, which the gpiod_set_value_cansleep on
the error path will attempt to deference.
Fix this issue by clearing reset_gpio before we head into the error
path.
