From eb52034436a58e742ceea0dcf2f003f83a3449a5 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Mon, 19 Feb 2024 09:38:47 -0300 Subject: i2c: 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 i2c_adapter_type and i2c_client_type variables to be constant structures as well, placing it into read-only memory which can not be modified at runtime. Signed-off-by: Ricardo B.
