#     Merge tag 'fbdev-v4.20' of https://github.com/bzolnier/linux
#     
#     Pull fbdev updates from Bartlomiej Zolnierkiewicz:
#      "No major changes to the subsystem itself, mainly fb drivers fixes &
#       cleanups (atyfb & udlfb updates stand out from the rest) + removal of
#       no longer needed old clps711xfb driver.
#     
#       Details:
#     
#        - update atyfb driver - improvements for ATI Mach64 chips: detect the
#          dot clock divider correctly on Sparc, fix display corruptions (due
#          to endianness issues and improper reading of accelerator
#          registers), optimize scrolling performance and also fix debugging
#          printks (Mikulas Patocka)
#     
#        - rewrite USB unplug handling in udlfb driver using framebuffer
#          subsystem reference counting (Mikulas Patocka)
#     
#        - fix support for native-mode display-timings in atmel_lcdfb driver
#          (Sam Ravnborg)
#     
#        - fix information leak & add missing access_ok() checks in sbuslib
#          (Dan Carpenter)
#     
#        - allow using GPIO expanders that can sleep in ssd1307fb driver
#          (Michal Vokáč)
#     
#        - convert omapfb driver to use GPIO descriptors instead of GPIO
#          numbers for Amstrad Delta board (Janusz Krzysztofik)
#     
#        - fix broken Kconfig menu dependencies (Randy Dunlap)
#     
#        - convert fbdev subsystem to use %pOFn instead of device_node.name
#          (Rob Herring)
#     
#        - remove the dead old CLPS711x LCD support driver (the new CLPS711x
#          LCD support driver is still available)
#     
#        - misc fixes (Jia-Ju Bai, Gustavo A. R. Silva)
#     
#        - misc cleanups (Mehdi Bounya, Nathan Chancellor, YueHaibing)"
