   - Resource leak fix for Maxim 77686
   - Possible suspend BUG() fix in OMAP USB TLL
   - Support for new Wolfson WM5110 Revision (D)
   - Testing of automatic assignment of of_node in mfd_add_device()
   - Reversion of the above when it started to cause issues
   - Remove legacy Platform Data from;
              TI TWL Core, Qualcomm SSBI and ST-E ABx500 Pinctrl
   - Clean-ups; tabbing issues, function name changes, 'drvdata = NULL'
              removal, unused uninitialised warning mitigation, error
              message clarity, removal of redundant/duplicate checks,
              licensing (GPL -> GPL2), coding consistency, duplicate
              function declaration, ret checks, commit corrections,
              redundant of_match_ptr() helper removal, spelling,
