      Merge "ARM: imx: fixes for 4.2" from Shawn Guo:
      
      The i.MX fixes for 4.2:
       - Correct compatible string for i.MX27 GPT which actually shares the
         same programming model as i.MX21 GPT rather than i.MX1 one.
       - Add missing #io-channel-cells property for i.MX23 LRADC device, which
         is required for the device to be an IIO provider.
       - Correct HSYNC/VSYNC pins and add ddc-i2c-bus property for TVE device
         on imx53-qsb to work properly.
       - Always enable PU domain if CONFIG_PM is not set.  This fixes a couple
         of failure scenarios which will hang the system if one of the devices
         in the PU domain is accessed.

      Minor fixes for omaps against v4.2-rc1. Mostly just minor dts changes
      except for a GPMC fix to not use names for probing devices. Also a
      one liner clean-up to remove unecessary return from a void function.
      
      The summary for the changes being:
      
      - Fix probe for GPMC devices by reoving limitations based on device
        name
      
      - Remove unnecessary return from a void function

      Now that we have simplefb support, we can enable it in our defconfig. Also
      enable the framebuffer console, so that we are sure that we actually get
      something displayed in any case.
      
      And while we're at it, enable the module support.

      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 ]

      Pull SCSI target updates from Nicholas Bellinger:
       "It's been a busy development cycle for target-core in a number of
        different areas.
      
        The fabric API usage for se_node_acl allocation is now within
        target-core code, dropping the external API callers for all fabric
        drivers tree-wide.
      
        There is a new conversion to RCU hlists for se_node_acl and
        se_portal_group LUN mappings, that turns fast-past LUN lookup into a
        completely lockless code-path.  It also removes the original
        hard-coded limitation of 256 LUNs per fabric endpoint.
      
        The configfs attributes for backends can now be shared between core
        and driver code, allowing existing drivers to use common code while
        still allowing flexibility for new backend provided attributes.
      
        The highlights include:
      
         - Merge sbc_verify_dif_* into common code (sagi)
         - Remove iscsi-target support for obsolete IFMarker/OFMarker
           (Christophe Vu-Brugier)
         - Add bidi support in target/user backend (ilias + vangelis + agover)

         - Handle target-core odd SGL mapping for data transfer memory

         - Move transport ID handling into target-core (hch)
         - Move task tag into struct se_cmd + support 64-bit tags (bart)
         - Convert se_node_acl->device_list[] to RCU hlist (nab + hch +
           paulmck)
         - Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch +
           paulmck)
         - Simplify target backend driver registration (hch)
         - Consolidate + simplify target backend attribute implementations
           (hch + nab)
         - Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch)
         - Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab)
         - Drop unnecessary core_tpg_register TFO parameter (nab)
         - Use 64-bit LUNs tree-wide (hannes)
