      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.

      Takashi Iwai authored
      Realtek codec driver contains some codes referring to the PCI
      subdevice IDs, but most of them are optional, typically for checking
      the codec name variants.  Add NULL checks appropriately so that it can
      work without PCI assignment.

      The default parent device can be obtained directly via card object, so
      we don't need to rely on pci->dev.parent.  Since there is no access to
      pci_dev, we can reduce the inclusion of linux/pci.h, too.
