6.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold johan+linaro@kernel.org
commit 3ab4e212a41c46668adf93c8d10d0d3d6de8f0e4 upstream.
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.
