Merge tag 'backlight-next-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/backlight

Pull backlight updates from Lee Jones:
 "Old Drivers
   - Remove driver for S6E63M0
   - Remove driver for LD9040

  Fix-ups
   - Trivial (email address update); adp*_bl
   - Use 'atomic' PWM API; pwm_bl

  Bug Fixes
   - Remove pointless boolen '&ptr' check; lm3639_bl"
