[PATCH 2/2] crypto: stm32/hash: remove interruptible condition for dma

From: Lionel Debieve
Date: Fri Jun 28 2019 - 07:27:31 EST


When DMA is used, waiting for completion must not be
interruptible as it can generate an error that is not handle
by the driver. There is no need to put the completion
interruptible in this driver.
