[PATCH v2 2/2] drm/panel: novatek,nt39016: Remove 'dev' field in priv struct

From: Paul Cercueil
Date: Thu Aug 20 2020 - 08:14:08 EST


There is already a 'struct device' pointer in the drm_panel structure,
that we can access easily from our priv structure, so there's no need
for a separate 'dev' field there.

v2: Don't initialize drm_panel->dev manually, it is done by
drm_panel_init().
