[PATCH 2/3] drm/panel-novatek-nt35510: Emit an error message if power off fails

[Uwe Kleine-König]

Returning an error code from a mipi_dsi remove callback fails, this is
silently ignored. (mipi_dsi_drv_remove() propagates the return value to
device_remove() which ignores it.) So emit an error code in the driver
remove function and return 0.
