6.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold johan+linaro@kernel.org
[ Upstream commit abf89bc4bb09c16a53d693b09ea85225cf57ff39 ]
The l12b and l15b supplies are used by components that are not (fully) described (and some never will be) and must never be disabled.
Mark the regulators as always-on to prevent them from being disabled, for example, when consumers probe defer or suspend.
