From eeb0074f36d1ab0729d06f1c56add9c7799679e2 Mon Sep 17 00:00:00 2001 From: Fernando Guzman Lugo <fernando.lugo@ti.com> Date: Wed, 29 Aug 2012 19:24:52 -0500 Subject: rpmsg: fix dma_free_coherent dev parameter dma_alloc/free_coherent APIs requires the platform specific remoteproc device as the device parameter. We are passing vdev->dev.parent to the dma_free_coherent function which is the generic rproc device and it is wrong, it has to be vdev->dev.parent->parent instead, same as when we call dma_alloc_coherent function.
