Subject: char/rtc: Use of_node_name_eq for node name comparisons
X-Git-Tag: v5.15~7298^2~11
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f88fd666051b08eb3f3118e2dd8508bf0247af4c;p=platform%2Fkernel%2Flinux-starfive.git

char/rtc: Use of_node_name_eq for node name comparisons

Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.

The open coded iterating thru the child node names is converted to use
for_each_child_of_node() instead.
