From 4dcc0f95ca2a9738e5e4e3bd7571fd95a9cbf272 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Mon, 19 Feb 2024 10:43:05 -0300 Subject: coresight: 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 coresight_dev_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.
