From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> [ Upstream commit eb7de496451bd969e203f02f66585131228ba4ae ] drm_mipi_dbi needs lots of DRM_KMS_HELPER support, so select that Kconfig symbol like it is done is most other uses, and the way that it was before MIPS_DBI was moved from tinydrm to its core location. Fixes these build errors: ld: drivers/gpu/drm/drm_mipi_dbi.o: in function `mipi_dbi_buf_copy': drivers/gpu/drm/drm_mipi_dbi.c:205: undefined reference to `drm_gem_fb_get_obj' ld: drivers/gpu/drm/drm_mipi_dbi.c:211: undefined reference to `drm_gem_fb_begin_cpu_access' ld: drivers/gpu/drm/drm_mipi_dbi.c:215: undefined reference to `drm_gem_fb_vmap' ld: drivers/gpu/drm/drm_mipi_dbi.c:222: undefined reference to `drm_fb_swab' ld: drivers/gpu/drm/drm_mipi_dbi.c:224: undefined reference to `drm_fb_memcpy' ld: drivers/gpu/drm/drm_mipi_dbi.c:227: undefined reference to `drm_fb_xrgb8888_to_rgb565' ld: drivers/gpu/drm/drm_mipi_dbi.c:235: undefined reference to `drm_gem_fb_vunmap' ld: drivers/gpu/drm/drm_mipi_dbi.c:237: undefined reference to `drm_gem_fb_end_cpu_access' ld: drivers/gpu/drm/drm_mipi_dbi.o: in function `mipi_dbi_dev_init_with_formats': ld: drivers/gpu/drm/drm_mipi_dbi.o:/X64/../drivers/gpu/drm/drm_mipi_dbi.c:469: undefined reference to `drm_gem_fb_create_with_dirty' Fixes: 174102f4de23 ("drm/tinydrm: Move mipi-dbi") Signed-off-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Reported-by: kernel test robot <lkp@xxxxxxxxx> Cc: Dillon Min <dillon.minfei@xxxxxxxxx> Cc: Linus Walleij <linus.walleij@xxxxxxxxxx> Cc: Sam Ravnborg <sam@xxxxxxxxxxxx> Cc: Noralf Trønnes <noralf@xxxxxxxxxxx> Cc: Thomas Zimmermann <tzimmermann@xxxxxxx> Cc: Thierry Reding <thierry.reding@xxxxxxxxx> Cc: dri-devel@xxxxxxxxxxxxxxxxxxxxx Cc: David Airlie <airlied@xxxxxxxx> Cc: Daniel Vetter <daniel@xxxxxxxx> Signed-off-by: Linus Walleij <linus.walleij@xxxxxxxxxx> Link: https://patchwork.freedesktop.org/patch/msgid/20220823004243.11596-1-rdunlap@xxxxxxxxxxxxx Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- drivers/gpu/drm/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/gpu/drm/Kconfig b/drivers/gpu/drm/Kconfig index ca868271f4c4..4e9b3a95fa7c 100644 --- a/drivers/gpu/drm/Kconfig +++ b/drivers/gpu/drm/Kconfig @@ -30,6 +30,7 @@ menuconfig DRM config DRM_MIPI_DBI tristate depends on DRM + select DRM_KMS_HELPER config DRM_MIPI_DSI bool -- 2.35.1
