Merge tag 'spi-v4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown:
"This release is mainly a collection of driver specific updates,
including a few nice cleanups to make drivers use more core features.
- automatically use the parent device to allocate DMA buffers if
there wasn't an explicitly configured device.
- fixes for leaks on allocation.
- a small piece of the start of SPI slave support, a feature that's
been on the cards for over a decade!"
