From 22265e236538f29e38df2411a12103aeefb3138b Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 26 Mar 2024 13:07:29 +0100 Subject: [PATCH] net: dwc_eth_qos: Constify st, eth-* values parsed out of DT Use const bool for the values parsed out of DT. Drop the duplicate assignment of false into those bool variables, assign them directly with the content parsed out of DT. Abbreviate the variable name too.
