Subject: drm/tilcdc: Remove tilcdc_verify_fb()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c72cc663649a7a6b860988e2b3a355e4280fd38d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/tilcdc: Remove tilcdc_verify_fb()

Remove tilcdc_verify_fb(). The tilcdc_verify_fb() function is not
needed because the same checks are implemented in
tilcdc_plane_atomic_check().
