   - omapfb:
       - Remove unused hdmi5_core_handle_irqs
       - Use of_property_present() to test existence of DT property
       - Use syscon_regmap_lookup_by_phandle_args
   - efifb: Change the return value type to void
   - lcdcfb: Use backlight helper
   - udlfb: Use const 'struct bin_attribute' callback
   - radeon: Use const 'struct bin_attribute' callbacks
   - sm501fb: Use str_enabled_disabled() helper in sm501fb_init_fb()"
