[PATCH 4.9 16/41] drm/vc4: Fix compilation error reported by kbuild test bot

From: Greg Kroah-Hartman
Date: Tue Apr 30 2019 - 07:39:59 EST


From: Maarten Lankhorst <maarten.lankhorst@xxxxxxxxxxxxxxx>

commit 462ce5d963f18b71c63f6b7730a35a2ee5273540 upstream.

A pointer to crtc was missing, resulting in the following build error:
drivers/gpu/drm/vc4/vc4_crtc.c:1045:44: sparse: sparse: incorrect type in argument 1 (different base types)
drivers/gpu/drm/vc4/vc4_crtc.c:1045:44: sparse: expected struct drm_crtc *crtc
drivers/gpu/drm/vc4/vc4_crtc.c:1045:44: sparse: got struct drm_crtc_state *state
drivers/gpu/drm/vc4/vc4_crtc.c:1045:39: sparse: sparse: not enough arguments for function vc4_crtc_destroy_state
