Char/Misc driver fixes for 6.3-final

Here are some last-minute tiny driver fixes for 6.3-final.  They
 include fixes for some fpga and iio drivers:
   - fpga bridge driver fix
   - fpga dfl error reporting fix
   - fpga m10bmc driver fix
   - fpga xilinx driver fix
   - iio light driver fix
   - iio dac fwhandle leak fix
   - iio adc driver fix
 
 All of these have been in linux-next for a few weeks with no reported
 problems.
