drm: msm: Fix build when legacy fbdev support isn't set (a2ca7789) · Commits · 戴 / test

The DRM_KMS_FB_HELPER config is selected only when DRM_MSM_FBDEV config is selected. The driver accesses drm_fb_helper_* functions even when legacy fbdev support is disabled in msm. Wrap around these functions with #ifdef checks to prevent build break. Signed-off-by:
