    Subject[PATCH 6.0 374/862] drm: fix drm_mipi_dbi build errors
    Date
    From: Randy Dunlap <rdunlap@infradead.org>

    [ 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'
