From 79a63c60a6a2ae589e44529401e0ab1150e9408a Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 25 Mar 2013 06:43:12 -0300 Subject: [PATCH] [media] media: move dvb-usb-v2/cypress_firmware.c to media/common Loading the cypress firmware is not dvb specific and should be common functionality. Move the source to media/common and make it a standalone module. As a result we can remove the dependency on dvb-usb in go7007, which has nothing to do with dvb.
