[PATCH v2 1/2] drm/panel: novatek,nt39016: Reorder calls in probe

From: Paul Cercueil
Date: Thu Aug 20 2020 - 08:13:21 EST


The drm_panel_of_backlight() function must be called after
drm_panel_init(), according to the function's documentation; otherwise
the backlight won't be properly initialized.

v2: New patch
