[PATCH v2 2/2] regulator: of: state who owns the array from of_regulator_bulk_get_all()

[Alexey Charkov <alchark@flipper.net>]

of_regulator_bulk_get_all() allocates the consumer array and hands it to
the caller, but never said so. Its own error path frees the array, while
regulator_bulk_free() only puts the regulators, so both callers release
the regulators and leak the array.

Spell the contract out in the kerneldoc.
