Subject: bridge: use list_for_each_entry() in netpoll functions
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4e3828c4bfd90b00a951cad7c8da27d1966beefe;p=openwrt%2Fstaging%2Fblogic.git

bridge: use list_for_each_entry() in netpoll functions

We don't delete 'p' from the list in the loop,
so we can just use list_for_each_entry().
