[PATCH] drm/panel: jdi-fhd-r63452: remove panel on DSI attach failure

[Myeonghun Pak]

The probe path calls drm_panel_add() before mipi_dsi_attach().

If mipi_dsi_attach() fails, the driver returns without calling

drm_panel_remove(), leaving the panel registered in the global DRM
panel list. The driver's .remove() callback does not handle this case
because failed probe does not transition through the normal bound-device
removal path.

Fix this by unwinding drm_panel_add() when mipi_dsi_attach() fails.
