Merge tag 'fbdev-v4.18' of git://github.com/bzolnier/linux
Pull fbdev updates from Bartlomiej Zolnierkiewicz:
"There is nothing really major here, few small fixes, some cleanups and
dead drivers removal:
- mark omapfb drivers as orphans in MAINTAINERS file (Tomi Valkeinen)
- add missing module license tags to omap/omapfb driver (Arnd
Bergmann)
- add missing GPIOLIB dependendy to omap2/omapfb driver (Arnd
Bergmann)
- convert savagefb, aty128fb & radeonfb drivers to use msleep & co.
(Jia-Ju Bai)
- allow COMPILE_TEST build for viafb driver (media part was reviewed
by media subsystem Maintainer)
- remove unused MERAM support from sh_mobile_lcdcfb and shmob-drm
drivers (drm parts were acked by shmob-drm driver Maintainer)
- remove unused auo_k190xfb drivers
- misc cleanups (Souptick Joarder, Wolfram Sang, Markus Elfring, Andy
Shevchenko, Colin Ian King)"
