From ab7add30ce63a7147f045f00c65a44c0f14ad6b2 Mon Sep 17 00:00:00 2001 From: Petr Kulhavy Date: Mon, 23 Mar 2015 21:35:01 +0100 Subject: [PATCH] dmaengine: edma: fixed wrongly initialized data parameter to the edma callback The "data" parameter passed indirectly to the edma_callback() should be edma_chan and not the dma_chan. This bug was so far harmless since the offset of struct dma_chan within struct edma_chan is 0. However as soon as someone changes struct edma_chan this would cause troubles.
