Subject: phy: broadcom: bcm-cygnus-pcie: Simplify with scoped for each OF child loop
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=e33525de6c3c7780564e0859ea6daef27309995b;p=users%2Fjedix%2Flinux-maple.git

phy: broadcom: bcm-cygnus-pcie: Simplify with scoped for each OF child loop

Use scoped for_each_available_child_of_node_scoped() when iterating over
device nodes to make code a bit simpler.
