Subject: 2.6.25-rc regression: bttv: oops on radio access (bisected)
Hi
2.6.25-rc7 kernel oopses on exec of "radio -c /dev/radio0".
I bisected it down to:
402aa76aa5e57801b4db5ccf8c7beea9f580bb1b is first bad commit
commit 402aa76aa5e57801b4db5ccf8c7beea9f580bb1b
Author: Douglas Schilling Landgraf <dougsland@...il.com>
Date: Thu Dec 27 22:20:58 2007 -0300
V4L/DVB (6911): Converted bttv to use video_ioctl2
