From b2d23256615c8f8b3215f0155b0234f0e310dfde Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Tue, 5 Mar 2024 16:55:24 -0300 Subject: [PATCH] ieee802154: cfg802154: make wpan_phy_class constant Since commit 43a7206b0963 ("driver core: class: make class_register() take a const *"), the driver core allows for struct class to be in read-only memory, so move the wpan_phy_class structure to be declared at build time placing it into read-only memory, instead of having to be dynamically allocated at boot time.
