As sun4i-backend is now a dedicated module, add an Kconfig option for it to make it optional, since some build may only use other engines. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> --- Changes in v7: - Adjusted the position of BACKEND makefile item. (It's now after common codes shared between sun4i-backend and sun8i-mixer.) drivers/gpu/drm/sun4i/Kconfig | 10 ++++++++++ drivers/gpu/drm/sun4i/Makefile | 3 ++- 2 files changed, 12 insertions(+), 1 deletion(-)
