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. -- Cheers, Stephen Rothwell
