      crypto: ccp - Provide support to autoload CCP driver · 6170511a
      Tom Lendacky authored
      Add the necessary module device tables to the platform support to allow
      for autoloading of the CCP driver. This will allow for the CCP's hwrng
      support to be available without having to manually load the driver. The
      module device table entry for the pci support is already present.

      crypto: omap-des - Fix unmapping of dma channels · acb33cc5
      Lokesh Vutla authored
      dma_unmap_sg() is being called twice after completing the
      task. Looks like this is a copy paste error when creating
      des driver.
      With this the following warn appears during boot:

      bluetooth: fix list handling · 9b284cbd
      Linus Torvalds authored
      Commit 835a6a2f ("Bluetooth: Stop sabotaging list poisoning")
      thought that the code was sabotaging the list poisoning when NULL'ing
      out the list pointers and removed it.
      
      But what was going on was that the bluetooth code was using NULL
      pointers for the list as a way to mark it empty, and that commit just
      broke it (and replaced the test with NULL with a "list_empty()" test on
      a uninitialized list instead, breaking things even further).
      
      So fix it all up to use the regular and real list_empty() handling
      (which does not use NULL, but a pointer to itself), also making sure to
      initialize the list properly (the previous NULL case was initialized
      implicitly by the session being allocated with kzalloc())
      
      This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong
      An.
      
      [ I would normally expect to get this through the bt tree, but I'm going
        to release -rc1, so I'm just committing this directly   - Linus ]
