From dab9ad5dcc35228983f5f0d22b179d45dc2ae05a Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dave.stevenson@raspberrypi.com>

Subject: [PATCH 623/828] dt: Create static regulators and clocks for camera
nodes
Unloading regulators through dynamic device tree doesn't work
as the regulators will unregister whilst clients are still
registered. Whilst the regulator framework does WARN when that
happens, the client putting the regulator then typically results
in a NULL dereference and badness.
Instead of creating regulators and clocks from the overlays,
create regulators and clocks for the sensors in the base DT.
