Subject: iio: adc: twl4030: Fix an error handling path in 'twl4030_madc_probe()'

From: Christophe JAILLET <[email protected]>

commit 245a396a9b1a67ac5c3228737c261b3e48708a2a upstream.

If 'devm_regulator_get()' fails, we should go through the existing error handling path instead of returning directly, as done is all the other error handling paths in this function.
