[PATCH] drm/vkms: replace deprecated functions in vkms_driver

From: Sidong Yang
Date: Wed Aug 26 2020 - 11:52:40 EST


gem_vm_ops and gem_free_object_unlocked function pointer is deprecated.
This patch replace these functions with drm_gem_object_funcs. And
functions used in drm_gem_object_funcs, vkms_gem_vm_ops and
vkms_gem_free_object, are not used other file but vkms_gem.c. So these
goes static functions. When creating vkms_gem_object, vkms_gem_funcs
is used for drm_gem_object.funcs.
