Pull ARM SoC fixes from Olof Johansson:
 "We had a small batch of fixes before -rc1, but here is a larger one.
  It contains a backmerge of 4.12-rc1 since some of the downstream
  branches we merge had that as base; at the same time we already had
  merged contents before -rc1 and rebase wasn't the right solution.

  A mix of random smaller fixes and a few things worth pointing out:

   - We've started telling people to avoid cross-tree shared branches if
     all they're doing is picking up one or two DT-used constants from a
     shared include file, and instead to use the numeric values on first
     submission. Follow-up moving over to symbolic names are sent in
     right after -rc1, i.e. here. It's only a few minor patches of this
     type.

   - Linus Walleij and others are resurrecting the 'Gemini' platform,
     and wanted a cut-down platform-specific defconfig for it. So I
     picked that up for them.

   - Rob Herring ran 'savedefconfig' on arm64, it's a bit churny but it
     helps people to prepare patches since it's a pain when defconfig
     and current savedefconfig contents differs too much.

   - Devicetree additions for some pinctrl drivers for Armada that were
     merged this window. I'd have preferred to see those earlier but
     it's not a huge deail.

  The biggest change worth pointing out though since it's touching other
  parts of the tree: We added prefixes to be used when cross-including
  DT contents between arm64 and arm, allowing someone to #include
  <arm/foo.dtsi> from arm64, and likewise. As part of that, we needed
  arm/foo.dtsi to work on arm as well. The way I suggested this to Heiko
  resulted in a recursive symlink.

  Instead, I've now moved it out of arch/*/boot/dts/include, into a
  shared location under scripts/dtc. While I was at it, I consolidated
  so all architectures now behave the same way in this manner.

  Rob Herring (DT maintainer) has acked it. I cc:d most other arch
  maintainers but nobody seems to care much; it doesn't really affect
  them since functionality is unchanged for them by default"

This patch fixes several issues:
   - if the 1st 'kzalloc' fails, we dereference a NULL pointer
   - if the 2nd 'kzalloc' fails, there is a memory leak
   - if 'sysfs_create_bin_file' fails there is also a memory leak

Fix it by adding a test after the first memory allocation and some error
handling paths to correctly free memory if needed.

  efi-pstore: Fix read iter after pstore API refactor

During the internal pstore API refactoring, the EFI vars read entry was
accidentally made to update a stack variable instead of the pstore
private data pointer. This corrects the problem (and removes the now
needless argument).
