From: Colin Ian King <colin.king@xxxxxxxxxxxxx> Currently the error check on the call to drm_dp_atomic_find_vcpi_slots is always false because an unsigned dm_new_connector_state->vcpi_slots is being checked for a less than zero. Fix this by casting this to an int on the comparison. Addresses-Coverity: ("Unsigned compared against 0") Fixes: 5133c6241d9c ("drm/amd/display: Add MST atomic routines") Signed-off-by: Colin Ian King <colin.king@xxxxxxxxxxxxx> --- drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c index 37c56156a116..00e730b8d98f 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c @@ -4866,7 +4866,7 @@ static int dm_encoder_helper_atomic_check(struct drm_encoder *encoder, mst_mgr, mst_port, dm_new_connector_state->pbn); - if (dm_new_connector_state->vcpi_slots < 0) { + if ((int)dm_new_connector_state->vcpi_slots < 0) { DRM_DEBUG_ATOMIC("failed finding vcpi slots: %d\n", (int)dm_new_connector_state->vcpi_slots); return dm_new_connector_state->vcpi_slots; } -- 2.20.1 _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
