[PATCH 2/3] drm/radeon/ttm: constify static vm_operations_struct

From: Rikard Falkeborn
Date: Tue Feb 09 2021 - 20:43:22 EST


The only usage of radeon_ttm_vm_ops is to assign its address to the
vm_ops field in the vm_area_struct struct. Make it const to allow the
compiler to put it in read-only memory
