    Subject[PATCH 2/2] drm: aspeed: select CONFIG_DRM_GEM_CMA_HELPER
    Date
    From: Arnd Bergmann <arnd@arndb.de>

    The aspeed driver uses the gem_cma_helper code, but does
    noto enforce enabling this through Kconfig:

    x86_64-linux-ld: drivers/gpu/drm/aspeed/aspeed_gfx_drv.o:(.rodata+0x2c8): undefined reference to `drm_gem_cma_prime_import_sg_table'
    x86_64-linux-ld: drivers/gpu/drm/aspeed/aspeed_gfx_drv.o:(.rodata+0x2d8): undefined reference to `drm_gem_cma_dumb_create'
    x86_64-linux-ld: drivers/gpu/drm/aspeed/aspeed_gfx_crtc.o: in function `aspeed_gfx_pipe_update':
    aspeed_gfx_crtc.c:(.text+0xe5): undefined reference to `drm_fb_cma_get_gem_obj'

    Add the same 'select' that is used in other such drivers.

    Fixes: 09717af7d13d ("drm: Remove CONFIG_DRM_KMS_CMA_HELPER option")
