From 68f5630ae15407d8d3daaadbbfbafbd319e3ecd4 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Mon, 19 Feb 2024 09:43:57 -0300 Subject: mmc: core: constify the struct device_type usage Since commit aed65af1cc2f ("drivers: make device_type const"), the driver core can properly handle constant struct device_type. Move the sdio_type, sd_type and mmc_type variables to be constant structures as well, placing it into read-only memory which can not be modified at runtime.
