This is a note to let you know that I've just added the patch titled
iio: adc: twl4030: Disable the vusb3v1 rugulator in the error
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: iio: adc: twl4030: Disable the vusb3v1 rugulator in the error
handling path of 'twl4030_madc_probe()'
Commit 7cc97d77ee8a has introduced a call to 'regulator_disable()' in the
.remove function.
So we should also have such a call in the .probe function in case of
error after a successful 'regulator_enable()' call.
Add a new label for that and use it.
