[PATCH] accel: constify the struct device_type usage

From: Ricardo B. Marliere
Date: Mon Feb 19 2024 - 14:51:19 EST


Since commit aed65af1cc2f ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the
accel_sysfs_device_minor variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
