Merge tag 'spi-v4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "This release is almost entirely driver changes, there's a couple of
  fixes in the core but otherwise it's all drivers:

   - fix for mixed dynamic and static bus number assignment.

   - fixes for some leaks arising from confusing lifetime rules during
     device unregistration and improved documentation to try to help
     avoid this in the future.

   - fixes to make the native chip select support for i.MX usable.

   - slave mode support for i.MX.

   - support for Coldfire MCF5441x DSPI, Renesas R8A7443/5 and
     Spreadtrum ADI"
