    Subject[PATCH 5.15 238/779] drm/panel: Fix build error when CONFIG_DRM_PANEL_SAMSUNG_ATNA33XC20=y && CONFIG_DRM_DISPLAY_HELPER=m
    Date
    From: Gao Chao <gaochao49@huawei.com>

    [ Upstream commit a67664860f7833015a683ea295f7c79ac2901332 ]

    If CONFIG_DRM_PANEL_SAMSUNG_ATNA33XC20=y && CONFIG_DRM_DISPLAY_HELPER=m,
    bulding fails:

    drivers/gpu/drm/panel/panel-samsung-atna33xc20.o: In function `atana33xc20_probe':
    panel-samsung-atna33xc20.c:(.text+0x744): undefined reference to
    `drm_panel_dp_aux_backlight'
    make: *** [vmlinux] Error 1

    Let CONFIG_DRM_PANEL_SAMSUNG_ATNA33XC20 select DRM_DISPLAY_DP_HELPER and
    CONFIG_DRM_DISPLAY_HELPER to fix this error.
