From a4735d40a5da96a637af6e5bf9f6ec8b9d996acd Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Sat, 9 Mar 2024 21:10:08 -0800 Subject: Input: make input_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 input_class structure to be declared at build time placing it into read-only memory, instead of having to be dynamically allocated at boot time.
