Subject: [PATCH 0/2] drm/panel: novatek-nt35560: Fix bug and clean up

This series does the following:
 - Add mipi_dsi_dcs_read_multi() to drm_mipi_dsi.c for improved error
   handling in drivers which use mipi_dsi_dcs_read() such as the
   novatek-nt35560 driver.
 - Fix a bug in nt35560_set_brightness() which causes the driver to
   incorrectly report that it "failed to disable display backlight".
 - Clean up novatek-nt35560 driver to use "multi" variants of MIPI
   functions which promote cleaner code.

If there's a reason that mipi_dsi_dcs_read_multi doesn't exist, I'm
happy to drop it.
