From: Ricardo B. Marliere Date: Tue, 5 Mar 2024 19:55:24 +0000 (-0300) Subject: ieee802154: cfg802154: make wpan_phy_class constant X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=b2d23256615c8f8b3215f0155b0234f0e310dfde;p=people%2Faperard%2Flinux.git 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.
