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: 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)

video/console: Update BIOS dates list for GPD win console rotation DMI quirk

2017-09-07T11:18:33+00:00

Recently produced GPD win devices have a new BIOS, research into the
changes in this BIOS has found a ChangeLog which also lists 2 previously
unknown BIOS dates.

Pull writeback error handling updates from Jeff Layton:
 "This pile continues the work from last cycle on better tracking
  writeback errors. In v4.13 we added some basic errseq_t infrastructure
  and converted a few filesystems to use it.

  This set continues refining that infrastructure, adds documentation,
  and converts most of the other filesystems to use it. The main
  exception at this point is the NFS client"

The VIOS LTH17 Cherry Trail bases netbook has its LCD panel mounted
rotated 90 degrees, add a DMI quirk for this.

fbcon: remove restriction on margin color

2017-09-04T14:00:49+00:00

This removes the restriction on the value range of the fbcon=margin:
parameter. The color value really depends on the driver being used.

fbcon: add fbcon=margin: command line option

2017-08-18T17:56:40+00:00

This adds a new command line option to select the fbcon margin color.

The motivation for this is screens where black does not blend into the
physical surroundings of the screen. For example, using an LCD (not the
backlit kind), white text on a black background is hard to read, so
inverting the colors is preferred. However, when you do this, most of the
screen is filled with white but the margins are still filled with black.
This makes a big, black, backwards 'L' on the screen. By setting
fbcon=margin:7, the margins will be filled with white and the LCD looks as
expected.

fbdev: fix 1bpp logo for unusual width

2017-08-18T17:56:40+00:00

This check is needed in the case where the width of the framebuffer
is not a multiple of 8 pixels. For example, LEGO MINDSTORMS EV3 has
a 178x128 1bpp display.

video/console: Add dmi quirk table for x86 systems which need fbcon rotation

2017-08-18T17:56:39+00:00

Some x86 clamshell design devices use portrait tablet screens and a
display engine which cannot rotate in hardware, so we need to rotate
the fbcon to compensate.

This commit adds a DMI based quirk table which is initially populated with
4 such devices: The Asus T100HA, GPD Pocket, the GPD win and the I.T.Works
TW891, so that the console comes up in the right orientation on these
devices OOTB.

Unfortunately these (cheap) devices also typically have quite generic DMI
data, so we match on a combination of DMI data, screen resolution and a
list of known BIOS dates to avoid false positives.

video: fbdev: Convert to using %pOF instead of full_name

2017-08-07T15:22:13+00:00

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.
