regulator: core: Let boot-on regulators be powered off
Boot-on regulators are always kept on because their use_count value is now incremented at boot time and never cleaned. Only increment count value for alway-on regulators. regulator_late_cleanup() is now able to power off boot-on regulators when unused. Fixes: 05f224ca6693 ("regulator: core: Clean enabling always-on regulators + their supplies") Signed-off-by: Pascal Paillet <p.paillet@st.com> Link: https://lore.kernel.org/r/20191113102737.27831-1-p.paillet@st.com Signed-off-by: Mark Brown <broonie@kernel.org>
