drm/gma500: fix error check
Reviewing this block of code in cdv_intel_dp_init()
ret = cdv_intel_dp_aux_native_read(gma_encoder, DP_DPCD_REV, ...
cdv_intel_edp_panel_vdd_off(gma_encoder);
if (ret == 0) {
/* if this fails, presume the device is a ghost */
DRM_INFO("failed to retrieve link info, disabling eDP\n");
drm_encoder_cleanup(encoder);
cdv_intel_dp_destroy(connector);
goto err_priv;
} else {
The (ret == 0) is not strict enough.
cdv_intel_dp_aux_native_read() returns > 0 on success
otherwise it is failure.
So change to <=
Fixes: d112a8163f83 ("gma500/cdv: Add eDP support")
