      ASoC: Fixes for v3.14
      
      A few fixes, all driver speccific ones.  The DaVinci ones aren't as
      clear as they should be from the subject lines on the commits but they
      fix issues which will prevent correct operation in some use cases and
      only affect that particular driver so are reasonably safe.

      Pull twi tracing fixes from Steven Rostedt:
       "Two urgent fixes in the tracing utility.
      
        The first is a fix for the way the ring buffer stores timestamps.
        After a restructure of the code was done, the ring buffer timestamp
        logic missed the fact that the first event on a sub buffer is to have
        a zero delta, as the full timestamp is stored on the sub buffer
        itself.  But because the delta was not cleared to zero, the timestamp
        for that event will be calculated as the real timestamp + the delta
        from the last timestamp.  This can skew the timestamps of the events
        and have them say they happened when they didn't really happen.
        That's bad.
      
        The second fix is for modifying the function graph caller site.  When
        the stop machine was removed from updating the function tracing code,
        it missed updating the function graph call site location.  It is still
        modified as if it is being done via stop machine.  But it's not.  This
        can lead to a GPF and kernel crash if the function graph call site
        happens to lie between cache lines and one CPU is executing it while
        another CPU is doing the update.  It would be a very hard condition to
        hit, but the result is severe enough to have it fixed ASAP"

      Btrfs: use right clone root offset for compressed extents · 93de4ba8
      Filipe David Borba Manana authored
      For non compressed extents, iterate_extent_inodes() gives us offsets
      that take into account the data offset from the file extent items, while
      for compressed extents it doesn't. Therefore we have to adjust them before
      placing them in a send clone instruction. Not doing this adjustment leads to
      the receiving end requesting for a wrong a file range to the clone ioctl,
      which results in different file content from the one in the original send
      root.

      i2c: mv64xxx: refactor message start to ensure proper initialization · 79970db2
      Wolfram Sang authored
      Because the offload mechanism can fall back to a standard transfer,
      having two seperate initialization states is unfortunate. Let's just
      have one state which does things consistently. This fixes a bug where
      some preparation was missing when the fallback happened. And it makes
      the code much easier to follow. To implement this, we put the check
      if offload is possible at the top of the offload setup function.

      Btrfs: unset DCACHE_DISCONNECTED when mounting default subvol · 3a0dfa6a
      Josef Bacik authored
      A user was running into errors from an NFS export of a subvolume that had a
      default subvol set.  When we mount a default subvol we will use d_obtain_alias()
      to find an existing dentry for the subvolume in the case that the root subvol
      has already been mounted, or a dummy one is allocated in the case that the root
      subvol has not already been mounted.  This allows us to connect the dentry later
      on if we wander into the path.  However if we don't ever wander into the path we
      will keep DCACHE_DISCONNECTED set for a long time, which angers NFS.  It doesn't
      appear to cause any problems but it is annoying nonetheless, so simply unset
      DCACHE_DISCONNECTED in the get_default_root case and switch btrfs_lookup() to
      use d_materialise_unique() instead which will make everything play nicely
      together and reconnect stuff if we wander into the defaul subvol path from a
      different way.  With this patch I'm no longer getting the NFS errors when
      exporting a volume that has been mounted with a default subvol set.  Thanks,

      Btrfs: fix max_inline mount option · feb5f965
      Mitch Harder authored
      Currently, the only mount option for max_inline that has any effect is
      max_inline=0.  Any other value that is supplied to max_inline will be
      adjusted to a minimum of 4k.  Since max_inline has an effective maximum
      of ~3900 bytes due to page size limitations, the current behaviour
      only has meaning for max_inline=0.
      
      This patch will allow the the max_inline mount option to accept non-zero
      values as indicated in the documentation.

      The reason is that we get to call cond_resched_lock(&head_ref->lock) while
      still holding @delayed_refs->lock.
      
      So it's different with __btrfs_run_delayed_refs(), where we do drop-acquire
      dance before and after actually processing delayed refs.
      
      Here we don't drop the lock, others are not able to add new delayed refs to
      head_ref, so cond_resched_lock(&head_ref->lock) is not necessary here.

      This reverts commit 10535314.
      Stephen Chivers reported this is broken as we will get a match
      entry '.type = "serial"' instead of the '.compatible = "ns16550"'
      in the following scenario:
      	serial0: serial@4500 {
      		compatible = "fsl,ns16550", "ns16550";
      	}
      
      	struct of_device_id of_platform_serial_table[] = {
      		{ .compatible = "ns8250",   .data = (void *)PORT_8250, },
      		{ .compatible = "ns16450",  .data = (void *)PORT_16450, },
      		{ .compatible = "ns16550a", .data = (void *)PORT_16550A, },
      		{ .compatible = "ns16550",  .data = (void *)PORT_16550, },
      		{ .compatible = "ns16750",  .data = (void *)PORT_16750, },
      		{ .compatible = "ns16850",  .data = (void *)PORT_16850, },
      		...
      		{ .type = "serial",         .data = (void *)PORT_UNKNOWN, },
      		{ /* end of list */ },
      	};
      
      So just revert this patch, we will use another implementation to find
      the best compatible match in a follow-on patch.
