From 1e25cd4729bd76662d02b142a6a7f8504bb6aea7 Mon Sep 17 00:00:00 2001 From: Mark Brown <broonie@linaro.org> Date: Tue, 25 Mar 2014 19:28:22 +0000 Subject: [PATCH] spi: Do not require a completion 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.
