[PATCH v2 3/5] iio: light: gp2ap020a00f: Enable the VCC supply

[Linus Walleij <linusw@kernel.org>]

Enable the VCC supply before accessing the device. Use the managed
helper so it is disabled on probe failure and removal. Let the regulator
framework provide a dummy regulator for an unspecified supply, and
propagate errors, including deferred probe.
