From 9f6f82ee61b23f0234fc83be363483bc4a65d99c Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Tue, 19 Jun 2012 22:31:04 -0300 Subject: [PATCH] [media] dvb_usb_v2: move dvb_usbv2_generic_rw() debugs behind define It is nice to have this debug, but as it generates very huge amount of traffic, better to make it conditional. Use define macro to disable it as I did not find out how to use dynamic debugs to dump variable length buffers like that.
