Subject: [PATCH] sysreset: socfpga: Use parent device for reading base address
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
This driver is a child of the rstmgr driver, both of which share the
same devicetree node. As a result, passing the child's udevice pointer
to dev_read_addr_ptr results in a failure of reading the #address-cells
property. Use the parent udevice pointer instead.
