Merge tag 'fbdev-v4.16' of git://github.com/bzolnier/linux 

Pull fbdev updates from Bartlomiej Zolnierkiewicz:
 "There is nothing really major here:

   - fix display-timings lookup in the Device Tree in atmel_lcdfb driver
     (Johan Hovold)

   - fix video mode and line_length to be set correctly in vfb driver
     (Pieter "PoroCYon" Sluys)

   - fix returning nonsensical values to the user-space on GIO_FONTX
     ioctl when using dummy console (Nicolas Pitre)

   - add missing license tag to mmpfb driver (Arnd Bergmann)

   - convert radeonfb and pxa3xx_gcu drivers to use ktime_get[_ts64]()
     instead of the deprecated do_gettimeofday() (Arnd Bergmann)

   - switch udlfb driver from using the pr_*() logging functions to the
     dev_*() ones + related cleanups (Ladislav Michl)

   - use __raw I/O accessors also on arm64 (Ji Zhang)

   - fix Kconfig help text for intelfb driver (Randy Dunlap)

   - do not duplicate features data in omapfb driver (Ladislav Michl)

   - misc cleanups (Colin Ian King, Markus Elfring, Rasmus Villemoes,
     Vasyl Gomonovych, Himanshu Jha, Michael Trimarchi)"
