Merge tag 'fbdev-v5.2' of git://github.com/bzolnier/linux

Pull fbdev updates from Bartlomiej Zolnierkiewicz:
 "Four small fixes for fb core, updates for udlfb, sm712fb, macfb and
  atafb drivers. Redundant code removals from amba-clcd and atmel_lcdfb
  drivers. Minor fixes/cleanups for other fb drivers

  Detailed summary:

   - fix regression in fbcon logo handling on 'quiet' boots (Andreas
     Schwab)

   - fix divide-by-zero error in fb_var_to_videomode() (Shile Zhang)

   - fix 'WARNING in __alloc_pages_nodemask' bug (Jiufei Xue)

   - list all PCI memory BARs as conflicting apertures (Gerd Hoffmann)

   - update udlfb driver: fix sleeping inside spinlock, add mutex around
     rendering calls and remove redundant code (Mikulas Patocka)

   - update sm712fb driver: fix SM720 support related issues (Yifeng Li)

   - update macfb driver: fix DAFB colour table pointer initialization
     and remove redundant code (Finn Thain)

   - update atafb driver: fix kexec support, use dev_*() calls instead
     of printk() and remove obsolete module support (Geert Uytterhoeven)

   - add support to mxsfb driver for skipping display initialization for
     flicker-free display takeover from bootloader (Melchior Franz)

   - remove Versatile and Nomadik board families support from amba-clcd
     driver as they are handled by DRM driver nowadays (Linus Walleij)

   - remove no longer needed AVR and platform_data support from
     atmel_lcdfb driver (Alexandre Belloni)

   - misc fixes (Colin Ian King, Julia Lawall, Gustavo A. R. Silva,
     Aditya Pakki, Kangjie Lu, YueHaibing)

   - misc cleanups (Enrico Weigelt, Kefeng Wang)"
