ASoC: Fixes for v4.3

A bunch of driver fixes plus one core fix which fixes problems with
misreporting values from _SX controls following a recent refactoring.
This had gone unnoticed as such controls are quite rare.

Reason is that regmap_update_bits() works a bit differently for
partially volatile registers than old homemade routine. Return

  drm/nouveau/gem: return only valid domain when there's only one

On nv50+, we restrict the valid domains to just the one where the buffer
was originally created. However after the buffer is evicted to system
memory, we might move it back to a different domain that was not
originally valid. When sharing the buffer and retrieving its GEM_INFO
data, we still want the domain that will be valid for this buffer in a
pushbuf, not the one where it currently happens to be.

This resolves fdo#92504 and several others. These are due to suspend
evicting all buffers, making it more likely that they temporarily end up
in the wrong place.

Pull intel-iommu bugfix from David Woodhouse:
 "This contains a single fix, for when the IOMMU API is used to overlay
  an existing mapping comprised of 4KiB pages, with a mapping that can
  use superpages.

  For the *first* superpage in the new mapping, we were correctly¹
  freeing the old bottom-level page table page and clearing the link to
  it, before installing the superpage.  For subsequent superpages,
  however, we weren't.  This causes a memory leak, and a warning about
  setting a PTE which is already set.

  ¹ Well, not *entirely* correctly.  We just free the page table pages
    right there and then, which is wrong.  In fact they should only be
    freed *after* the IOTLB is flushed so we know the hardware will no
    longer be looking at them....  and in fact I note that the IOTLB
    flush is completely missing from the intel_iommu_map() code path,
    although it needs to be there if it's permitted to overwrite
    existing mappings.

    Fixing those is somewhat more intrusive though, and will probably
    need to wait for 4.4 at this point"

If request_key() is used to find a keyring, only do the search part - don't
do the construction part if the keyring was not found by the search.  We
don't really want keyrings in the negative instantiated state since the
rejected/negative instantiation error value in the payload is unioned with
keyring metadata.

Now the kernel gives an error:

	request_key("keyring", "#selinux,bdekeyring", "keyring", KEY_SPEC_USER_SESSION_KEYRING) = -1 EPERM (Operation not permitted)
