spi: Do not require a completion
PATCH 1/1 spi: Do not require a completion
From: Mark Brown <[email protected]>
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.
