From 3f98387efa9333c5765d36e144c47c107d6ba64a Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Thu, 1 May 2008 10:31:12 -0300 Subject: V4L/DVB (7854): cx18/ivtv: improve and fix out-of-memory handling - don't show kernel backtrace when the allocation of the buffers fails: the normal ivtv/cx18 messages are clear enough and the backtrace scares users. - fix cleanup after the buffer allocation fails (caused kernel panic).
