Hi all,
I'm having difficulty getting dvb_ttpci to work after upgrading to Kernel
version 2.6.16.20 and the latest mercurial snapshot.
I get the following error:
saa7146: register extension 'dvb'.
ACPI: PCI Interrupt 0000:00:14.0[A] -> Link [LNKB] -> GSI 12 (level, low) ->

Poking around a bit I find that kobj->dentry is a null pointer in
sysfs_create_link.
Hoping someone can help,
Chris
