Subject: sysreset: socfpga: Use parent device for reading base address
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=9ebca7095bdbb2843a37b1f36d7896a6cb21e4ab;p=u-boot.git

sysreset: socfpga: Use parent device for reading base address

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.
