From 2c720b492c59b070930aa1be8bef6e256d3bf4b2 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Mon, 19 Feb 2024 09:47:28 -0300 Subject: dax: 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 dax_mapping_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime. Cc: Greg Kroah-Hartman Signed-off-by: Ricardo B.
