+Subject: regulator: core: Add regulator_is_equal() helper
+
+From: Marek Vasut <marex@denx.de>
+
+commit b059b7e0ec3208ff1e17cff6387d75a9fbab4e02 upstream.
+
+Add regulator_is_equal() helper to compare whether two regulators are
+the same. This is useful for checking whether two separate regulators
+in a driver are actually the same supply.
