Subject: [PATCH] drm/panel: asus-z00t-tm5p5-n35596: transition to mipi_dsi wrapped functions
Use functions introduced in commit 966e397e4f60 ("drm/mipi-dsi:
Introduce mipi_dsi_*_write_seq_multi()") and commit f79d6d28d8fe
("drm/mipi-dsi: wrap more functions for streamline handling") for the
asus-z00t-tm5p5-n35596 panel.
