From 92781f10e32b27b8bc90d8deb1194de7e942a2f7 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 29 Mar 2016 16:33:42 -0700 Subject: [PATCH] regulator: core: Log when we bring constraints into range This aids in debugging problems triggered by the regulator core applying its constraints, we could potentially crash immediately after updating the voltage if the constraints are buggy.
