Second set of IIO fixes for IIO in the 4.11 cycle.

Browse source 
This series consists of fixes that either came in after the merge window
 had opened or are fixes for work that merged during the merge window so had
 to wait for that to hit mainline.
 
 * 104-quad-8
   - Fix an off by one error in the register address for the flag register.
 * rcar-gyroadc
   - protect against possible issues in future by dealing with childmode not
     being in a valid state.  This also deals with some build warnings.
 * xilinx
   - fix some error handling paths to ensure resources are released in
     reverse order of being acquired.
