From b50b3e0732845563626c8e40f8b6eed92172cd10 Mon Sep 17 00:00:00 2001 From: Malcolm Priestley Date: Thu, 2 Aug 2012 19:31:53 -0300 Subject: [PATCH] [media] dvb_usb_lmedm04: don't crash if firmware is not loaded There is a missing error handling when no firmware file found. It seems that this is more of a problem with udev-182+. However, so far udev-182 is only a problem on first ever plug.
