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.

Silva) # # - misc cleanups (Mehdi Bounya, Nathan Chancellor, YueHaibing)" # # * tag 'fbdev-v4.20' of https://github.com/bzolnier/linux: (22 commits) # video: fbdev: remove redundant 'default n' from
