From 5ff331cb050f52361ec40512cc6d87f4923ed29f Mon Sep 17 00:00:00 2001

Subject: [PATCH] drm/panel: ilitek-ili9881c: Clean up on
mipi_dsi_attach failure
mipi_dsi_attach is allowed to fail, and currently the probe
code doesn't clean up (mainly drm_panel_remove) if this happens.
Add cleanup code on failure.
