Get rid of those warnings by adding extra blank lines:

    Documentation/driver-api/dmaengine/provider.rst:270: WARNING: Unexpected indentation.
    Documentation/driver-api/dmaengine/provider.rst:273: WARNING: Block quote ends without a blank line; unexpected unindent.
    Documentation/driver-api/dmaengine/provider.rst:288: WARNING: Unexpected indentation.
    Documentation/driver-api/dmaengine/provider.rst:290: WARNING: Block quote ends without a blank line; unexpected unindent.

While here, use parenthesis after get_metadata_ptr/set_metadata_len,
as, if some day someone adds a kerneldoc markup for those, it
should automatically generate a cross-reference to them.

The bullet list documenting the 'struct dma_device' fields has several
nesting errors, making it render improperly. It also has incoherent
formatting: some fields have a description in the same bullet, some in
a sub-bullet.

Fix both to have a correct and coherent formatting.
