From 373459eee0cd79f775ef9874395bb37638154777 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 14 Feb 2013 11:00:19 +0200 Subject: edma: do not waste memory for dma_mask Accordingly to commentary in the platform_device_register_full the memory allocated for dma_mask will not going to be freed. That's why is better to assign dma_mask afterwards.
