Pull spi fixes from Mark Brown:
 "As well as the usual driver fixes there's a couple of non-trivial core
  fixes in here:

   - Fixes for issues reported by Julia Lawall in the changes that were
     sent last time to fix interaction between the bus lock and the
     locking done for the SPI thread.  I'd let this one cook for a while
     to make sure nothing else came up in testing.

   - A fix from Sien Wu for arithmetic overflows when calculating the
     timeout for larger transfers (espcially common with slow buses with
     flashes on them)"
