+
+commit 4722f463896cc0ef1a6f1c3cb2e171e949831249 upstream.
+
+The return value was never initialized so the cleanup code executed when
+it isn't even necessary.
+
+Just add proper error handling.

+Subject: of: base: Improve argument length mismatch error
+
+From: Baruch Siach <baruch@tkos.co.il>
+
+commit 5d05b811b5acb92fc581a7b328b36646c86f5ab9 upstream.
+
+The cells_name field of of_phandle_iterator might be NULL. Use the
+phandle name instead. With this change instead of:
+
+ OF: /soc/pinctrl@1000000: (null) = 3 found 2
+
+We get:
+
+ OF: /soc/pinctrl@1000000: phandle pinctrl@1000000 needs 3, found 2
+
+Which is a more helpful messages making DT debugging easier.
+
+In this particular example the phandle name looks like duplicate of the
+same node name. But note that the first node is the parent node
+(it->parent), while the second is the phandle target (it->node). They
+happen to be the same in the case that triggered this improvement. See
+commit 72cb4c48a46a ("arm64: dts: qcom: ipq6018: Fix gpio-ranges
+property").
