Merge tag 'dma-mapping-5.2' of git://git.infradead.org/users/hch/dma-mapping
Pull DMA mapping updates from Christoph Hellwig:
- remove the already broken support for NULL dev arguments to the DMA
API calls
- Kconfig tidyups
* tag 'dma-mapping-5.2' of git://git.infradead.org/users/hch/dma-mapping:
dma-mapping: add a Kconfig symbol to indicate arch_dma_prep_coherent presence
dma-mapping: remove an unnecessary NULL check
x86/dma: Remove the x86_dma_fallback_dev hack
dma-mapping: remove leftover NULL device support
arm: use a dummy struct device for ISA DMA use of the DMA API
pxa3xx-gcu: pass struct device to dma_mmap_coherent
gbefb: switch to managed version of the DMA allocator
da8xx-fb: pass struct device to DMA API functions
parport_ip32: pass struct device to DMA API functions
dma: select GENERIC_ALLOCATOR for DMA_REMAP
