Merge tag 'backlight-next-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/backlight

Pull backlight updates from Lee Jones:
 "New Drivers:
   - Add support for Kinetic KTD2801 Backlight

  Fix-ups:
   - Fix include lists; alphabetise, remove unused, explicitly add used
   - Device Tree binding adaptions/conversions/creation
   - Use dev_err_probe() to clean-up error paths
   - Use/convert to new/better APIs/helpers/MACROs instead of hand-rolling implementations

  Bug Fixes:
   - Fix changes of NULL pointer dereference
   - Remedy a bunch of logic errors
   - Initialise (zero) Backlight properties data structures"

+description: |
+  The Kinetic Technologies KTD2801 is a LED backlight driver controlled
+  by a single GPIO line. The driver can be controlled with a PWM signal
+  or by pulsing the GPIO line to set the backlight level. This is called
+  "ExpressWire".
