On Falcon, Atari frame buffer initialization relies on preprogrammed
register values.  These register values are changed to blank the
console.

Hence when using kexec to boot into a new kernel while the console is
blanked, the new kernel cannot determine the current video
configuration, and the Atari frame buffer driver fails to initialize:

    atafb: phys_screen_base 6ce000 screen_len 4096

Fix this by doing a straight-forward conversion of the driver to a
platform device driver, and adding a shutdown handler that unblanks the
display.

  bugs) on top.

  Summary:

   - Revert the extended use of gpio_set_config() and think about how we
     can do this properly.

   - Fix up the SPI CS GPIO handling so it now works properly on the SPI
     bus children, as intended.

   - Error paths and driver fixes"

* tag 'gpio-v5.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:

  gpio: amd-fch: Fix bogus SPDX identifier
  gpio: adnp: Fix testing wrong value in adnp_gpio_direction_input
  gpio: exar: add a check for the return value of ida_simple_get fails

If userspace doesn't end the input with a newline (which can easily
happen if the write happens from a C program that does write(fd,
iface, strlen(iface))), we may end up including garbage from a
previous, longer value in the device_name. For example

# cat device_name

# printf 'eth12' > device_name
# cat device_name
eth12
# printf 'eth3' > device_name
# cat device_name
eth32

I highly doubt anybody is relying on this behaviour, so switch to
simply copying the bytes (we've already checked that size is <
IFNAMSIZ) and unconditionally zero-terminate it; of course, we also
still have to strip a trailing newline.

This is also preparation for future patches.

  virtual box decided to change their api in their latest release in a
  way that broke the existing kernel code, despite saying that they were
  never going to do that. So this is a bit of a "new feature", but is
  good to get merged so that 5.1 will work with the latest release. The
  changes are not large and of course virtual box "swears" they will not
  break this again, but no one is holding their breath here.

  All of these have been in linux-next for a while with no reported
  issues"

Pull SCSI fixes from James Bottomley:
 "Thirteen fixes, seven of which are for IBM fibre channel and three
  additional for fairly serious bugs in drivers (qla2xxx, mpt3sas,
  aacraid).

  Of the three core fixes, the most significant is probably the missed
  run queue causing an indefinite hang. The others are fixing a
  potential use after free on device close and silencing an incorrect
  warning"

Pull sound fixes from Takashi Iwai:
 "The important fixes at this time are a couple fixes in ALSA core: a
  fix for PCM is about the OOB access in PCM OSS plugins that has been
  for long time, but hasn't hit so often until now just because we
  allocated a large buffer via vmalloc(), and surfaced more often after
  switching to kvmalloc(). Another fix is for a long-standing PCM
  problem wrt racy PM resume.

  Others are trivial nospec coverage and usual HD-audio quirks"
