Merge tag 'spi-fix-v4.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi fixes from Mark Brown:
"The usual small smattering of driver specific fixes. A few bits that
stand out here:
- the R-Car patches adding fallbacks are just adding new compatible
strings to the driver so that device trees are written in a more
robustly future proof fashion, this isn't strictly a fix but it's
just new IDs and it's better to get it into mainline sooner to
improve the ABI
- the DesignWare "switch to new API part 2" patch is actually a
misleadingly titled fix for a bit that got missed in the original
conversion"
* tag 'spi-fix-v4.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
spi: davinci: use dma_mapping_error()
spi: spi-axi: Free resources on error path
spi: pxa2xx: add missed break
spi: dw-mid: switch to new dmaengine_terminate_* API (part 2)
spi: dw: Make debugfs name unique between instances
spi: sh-msiof: Do not use C++ style comment
spi: armada-3700: Set mode bits correctly
spi: armada-3700: fix unsigned compare than zero on irq
spi: sh-msiof: Add R-Car Gen 2 and 3 fallback bindings
spi: SPI_FSL_DSPI should depend on HAS_DMA
