Subject: [PATCH 0/3] Additional fixes for dma coherent allocator

Additional fixups to improve the documentation and make the read/write
macros return Result as suggested by Andreas Hindborg as well as support
for reading and writing large blocks of data.

Abdiel Janulgue (3):
  rust: dma: be consistent in using the `coherent` nomenclature
  rust: dma: convert the read/write macros to return Result
  rust: dma: add as_slice/write functions for CoherentAllocation
