Whenever I mount a cdrom with 2.1.13 I get this message:
DEBUG: sr_audio: result for ioctl 5305: fffffff2
which is saying that the code for CDROMREADTOCHDR returned
-EFAULT.
This is coming from the sr_audio_ioctl function in sr_ioctl.c
where it says:
if (copy_to_user(...))
return -EFAULT;
Shouldn't this be
if (!copy_to_user(...))
If I'm right, here's a simple patch.
