While _regulator_is_enabled() takes the enable GPIO into account, regulator_late_cleanup() was not doing that. This resulted in a false positive, e.g. when a GPIO-controlled fixed regulator was used, which was not enabled at boot time, e.g. reg_disp_1v2: reg_disp_1v2 { compatible = "regulator-fixed"; regulator-name = "display_1v2"; regulator-min-microvolt = <1200000>; regulator-max-microvolt = <1200000>; gpio = <&tlmm 148 0>; enable-active-high; }; Such regulator doesn't have an is_enabled() operation. Nevertheless it's state can be determined based on the enable GPIO. The check in regulator_late_cleanup() wrongly assumed that the regulator is on and tried to disable it.

Update qcom_smd-regulator's probe function to mimic what rpmh-regulator does to address a couple of issues: - Probe defer now works correctly, before it used to, well, kinda just die.. This fixes reliable probing on (at least) PM8994, because Linux apparently cannot deal with supply map dependencies yet.. - Regulator data is now matched more sanely: regulator data is matched against each individual regulator node name and throwing an -EINVAL if data is missing, instead of just assuming everything is fine and iterating over all subsequent array members. - status = "disabled" will now work for disabling individual regulators in DT. Previously it didn't seem to do much if anything at all.
