Subject: stmmac: pci: split out common_default_data() helper
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=70fe4432bb360207fba04b4137f330a7a109f7a6;p=openwrt%2Fstaging%2Fblogic.git

New helper is added in order to prevent misconfiguration happened
for one of the platforms when configuration data is expanded.
