Fix bug in novatek-nt35560 driver's nt35560_set_brightness() which causes the driver to incorrectly report that it "failed to disable display backlight".
Add mipi_dsi_dcs_read_multi() to drm_mipi_dsi.c for improved error handling in drivers which use mipi_dsi_dcs_read() multiple times in a row. Add mipi_dsi_dcs_write_var_seq_multi() and mipi_dsi_generic_write_var_seq_multi() to drm_mipi_dsi.h to allow drivers to more conveniently construct MIPI payloads at runtime. Clean up novatek-nt35560 driver to use "multi" variants of MIPI. Changes to v4: - Replace "non-static" in kerneldoc comment with "non-constant" Changes to v3: - Fix incorrect Fixes tag. The bug was introduced by an earlier commit. - Minor formatting improvements. Changes to v2: - Separate bug fix into its own commit for backporting. - Add var_seq_multi() variants of MIPI write macros for sending non-static MIPI messages. - Minor formatting improvements.
