From 8e830bd17e945e74964a5b61353d74e34c0791cd Mon Sep 17 00:00:00 2001 From: Andy Gross Date: Fri, 29 Jan 2016 22:06:50 -0600 Subject: [PATCH] spi: qup: Fix transaction done signaling Wait to signal done until we get all of the interrupts we are expecting to get for a transaction. If we don't wait for the input done flag, we can be inbetween transactions when the done flag comes in and this can mess up the next transaction.
