From e5853918d6dc971957b7daf2a2abd4b7eba37887 Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Sun, 6 Sep 2015 08:42:12 -0300 Subject: [PATCH] [media] pxa_camera: trivial move of dma irq functions This moves the dma irq handling functions up in the source file, so that they are available before DMA preparation functions. It prepares the conversion to DMA engine, where the descriptors are populated with these functions as callbacks.
