[PATCH] spi: Do not require a completion

[Mark Brown <broonie@xxxxxxxxxx>]

From: Mark Brown <broonie@xxxxxxxxxx>

There is no real reason why we require transfers to have a completion and
the only user of the completion now checks to see if one has been provided
before using it so stop enforcing this. This makes it more convenient for
drivers to chain multiple asynchronous transfers together.
