From faf3b8014c357d71c7a9414302e217a1dd1679af Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Tue, 5 Mar 2024 16:49:30 -0300 Subject: [PATCH] mmc: core: make mmc_host_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 mmc_host_class structure to be declared at build time placing it into read-only memory, instead of having to be dynamically allocated at boot time.
