+Subject: regulator: Fix memory garbage dev_err printout.
+
+From: Russ Dill <Russ.Dill@ti.com>
+
+commit 9c7b4e8a8ad2624106fbf690fa97ab9c8c9bfa88 upstream.
+
+commit dd8004af: 'regulator: core: Log when a device causes a voltage
+constraint fail', tried to print out some information about the
+check consumer min/max uV fixup, however, it uses a garbage pointer
+left over from list_for_each_entry leading to boot messages in the
+form:
+
+'[    2.079890] <RANDOM ASCII>: Restricting voltage, 3735899821-4294967295uV'
+
+Because it references regulator->dev, it could potentially read memory from
+anywhere causing a panic.
+
+This patch instead uses rdev and the updated min/max uV values.
