-Subject: [PATCH] Revert "regulator: resolve supply after creating regulator"
-
-This commit prevents the serial console from working on the Rock Pi 4
-for some reason. It *appears* to possibly be fixed by some other commit
-upstream, but after a lot of head scratching and bisecting, I was unable
-to find which one, so just revert it for now and we can deal with it
-later.
-
-This reverts commit 96c6b5d5775637b3095ef934f871044811fd4db7.
