From 1961511c8e662417f7fd3a111c9980d415413c28 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Tue, 5 Mar 2024 16:40:23 -0300 Subject: [PATCH] remoteproc: Make rproc_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 rproc_class structure to be declared at build time placing it into read-only memory, instead of having to be dynamically allocated at boot time.
