From d5ff5061c35448525fcb38950f06af6b9ae12c04 Mon Sep 17 00:00:00 2001 From: Stefano Stabellini Date: Thu, 13 Apr 2017 14:04:22 -0700 Subject: [PATCH] xen/arm,arm64: rename __generic_dma_ops to xen_get_dma_ops Now that __generic_dma_ops is a xen specific function, rename it to xen_get_dma_ops. Change all the call sites appropriately.
