From 7eccf41b3bacb97092bffb23853529277c20e46a Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Sat, 17 Feb 2024 17:13:33 -0300 Subject: [PATCH] net: wwan: 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 wwan_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.
