patch "iio: adc128s052: Fix the error handling path of 'adc128_probe()'" added to staging-linus

This is a note to let you know that I've just added the patch titled

iio: adc128s052: Fix the error handling path of 'adc128_probe()'

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: adc128s052: Fix the error handling path of 'adc128_probe()'

A successful 'regulator_enable()' call should be balanced by a corresponding 'regulator_disable()' call in the error handling path of the probe, as already done in the remove function.

Update the error handling path accordingly.
