Merge tag 'fbdev-v4.14' of git://github.com/bzolnier/linux

Pull fbdev updates from Bartlomiej Zolnierkiewicz:

 - make fbcon a built-time depency for fbdev (fbcon was tristate option
   before, now it is a bool) - this is a first step in preparations for
   making console_lock usage saner (currently it acts like the BKL for
   all things fbdev/fbcon) (Daniel Vetter)

 - add fbcon=margin:<color> command line option to select the fbcon
   margin color (David Lechner)

 - add DMI quirk table for x86 systems which need fbcon rotation
   (devices like Asus T100HA, GPD Pocket, the GPD win and the I.T.Works
   TW891) (Hans de Goede)

 - fix 1bpp logo support for unusual width (needed by LEGO MINDSTORMS
   EV3) (David Lechner)

 - enable Xilinx FB driver for ARM ZynqMP platform (Michal Simek)

 - fix use after free in the error path of udlfb driver (Anton Vasilyev)

 - fix error return code handling in pxa3xx_gcu driver (Gustavo A. R.
   Silva)

 - fix bootparams.screeninfo arguments checking in vgacon (Jan H.
   Schönherr)

 - do not leak uninitialized padding in clk to userspace in the debug
   code of atyfb driver (Vladis Dronov)

 - fix compiler warnings in fbcon code and matroxfb driver (Arnd
   Bergmann)

 - convert fbdev susbsytem to using %pOF instead of full_name (Rob
   Herring)

 - structures constifications (Arvind Yadav, Bhumika Goyal, Gustavo A.
   R. Silva, Julia Lawall)

 - misc cleanups (Gustavo A. R. Silva, Hyun Kwon, Julia Lawall, Kuninori
   Morimoto, Lynn Lei)
