Subject: linux-next: build failure after merge of the drm-misc tree

Hi all,

After merging the drm-misc tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/gpu/drm/drm_cache.c: In function 'drm_need_swiotlb':
drivers/gpu/drm/drm_cache.c:202:6: error: implicit declaration of function 'mem_encrypt_active' [-Werror=implicit-function-declaration]
  202 |  if (mem_encrypt_active())
      |      ^~~~~~~~~~~~~~~~~~

Caused by commit

  3abc66706385 ("drm: Implement drm_need_swiotlb() in drm_cache.c")

I have used the drm-misc tree from next-20210107 again for today.
