From d921620e03c58bd83c4b345e36a104988d697f0d Mon Sep 17 00:00:00 2001 From: Tom Lendacky Date: Tue, 26 May 2015 13:06:24 -0500 Subject: [PATCH] crypto: ccp - Remove manual check and set of dma_mask pointer The underlying device support will set the device dma_mask pointer if DMA is set up properly for the device. Remove the check for and assignment of dma_mask when it is null. Instead, just error out if the dma_set_mask_and_coherent function fails because dma_mask is null.
