ASoC: Fixes for v4.15

This is a fairly large set of fixes, they've been delayed partly as more
and more keep coming in.  Most of them are very small driver specific
fixes, the biggest individual thing is the revert of the rcar IOMMU
support - it was causing problems and there wasn't the confidence that
it could be resolved sensibly.  There's also a relatively large change
in the Freescale SSI controller which resolves some issues with the
AC'97 mode, these aren't that large in the grand scheme of things and
reflect some fairly thorough review and testing.

      ASoC: rt5514-spi: only enable wakeup when fully initialized · 20220945
      由 Brian Norris 提交于 
      If an rt5514-spi device is probed but the platform hasn't linked it in,
we might never fully request the SPI IRQ, nor configure the rt5514 DSP,
but we still might try to enable the SPI IRQ (enable_irq_wake()). This
is bad, and among other things, can cause the interrupt to trigger every
time we try to suspend the system (e.g., because the interrupt trigger
setting was never set properly).

Instead of setting our wakeup capabilities in the SPI driver probe
routine, let's wait until we've actually requested the IRQ.

Fixes issues seen on the "kevin" Chromebook (Samsung Chromebook Plus).

      ASoC: nau8825: fix issue that pop noise when start capture · d070f7c7
      由 Abhijeet Kumar 提交于 
      In skylake platform, we hear a loud pop noise(0 dB) at start of
audio capture power up sequence. This patch removes the pop noise
from the recording by adding a delay before enabling ADC.

      ALSA: usb-audio: Fix the missing ctl name suffix at parsing SU · 5a15f289
      由 Takashi Iwai 提交于 
      The commit 89b89d12 ("ALSA: usb-audio: Add check return value for
usb_string()") added the check of the return value from
snd_usb_copy_string_desc(), which is correct per se, but it introduced
a regression.  In the original code, either the "Clock Source",
"Playback Source" or "Capture Source" suffix is added after the
terminal string, while the commit changed it to add the suffix only
when get_term_name() is failing.  It ended up with an incorrect ctl
name like "PCM" instead of "PCM Capture Source".

Also, even the original code has a similar bug: when the ctl name is
generated from snd_usb_copy_string_desc() for the given iSelector, it
also doesn't put the suffix.

This patch addresses these issues: the suffix is added always when no
static mapping is found.  Also the patch tries to put more comments
and cleans up the if/else block for better readability in order to
avoid the same pitfall again.

      Revert "mm: replace p??_write with pte_access_permitted in fault + gup paths" · f6f37321
      由 Linus Torvalds 提交于 
      This reverts commits 5c9d2d5c, c7da82b8, and e7fe7b5c.

We'll probably need to revisit this, but basically we should not
complicate the get_user_pages_fast() case, and checking the actual page
table protection key bits will require more care anyway, since the
protection keys depend on the exact state of the VM in question.

Particularly when doing a "remote" page lookup (ie in somebody elses VM,
not your own), you need to be much more careful than this was.  Dave
Hansen says:

 "So, the underlying bug here is that we now a get_user_pages_remote()
  and then go ahead and do the p*_access_permitted() checks against the
  current PKRU. This was introduced recently with the addition of the
  new p??_access_permitted() calls.

  We have checks in the VMA path for the "remote" gups and we avoid
  consulting PKRU for them. This got missed in the pkeys selftests
  because I did a ptrace read, but not a *write*. I also didn't
  explicitly test it against something where a COW needed to be done"

It's also not entirely clear that it makes sense to check the protection
key bits at this level at all.  But one possible eventual solution is to
make the get_user_pages_fast() case just abort if it sees protection key
bits set, which makes us fall back to the regular get_user_pages() case,
which then has a vma and can do the check there if we want to.

We'll see.

Somewhat related to this all: what we _do_ want to do some day is to
check the PAGE_USER bit - it should obviously always be set for user
pages, but it would be a good check to have back.  Because we have no
generic way to test for it, we lost it as part of moving over from the
architecture-specific x86 GUP implementation to the generic one in
commit e585513b ("x86/mm/gup: Switch GUP to the generic
get_user_page_fast() implementation").
