From 6b4a16c36400143efe4b693bbdf65c0367b7e1ac Mon Sep 17 00:00:00 2001 From: Sean Young Date: Mon, 20 Jan 2014 19:10:44 -0300 Subject: [media] mceusb: improve error logging A number of recent bug reports involve usb_submit_urb() failing which was only reported with debug parameter on. In addition, remove custom debug function.
