Subject: [PATCH v2 2/4] soc: sunxi: sram: Only iterate over SRAM children
Date:   Tue,  2 Aug 2022 00:32:11 -0500

Now that a "regulators" child is accepted by the controller binding, the
debugfs show routine must be explicitly limited to "sram" children.
Otherwise, it will crash because the "regulators" node has no address.
