Hi,

I just noticed that v4l-experimental does not compile anymore against
kernel 2.6.26. It seems the support of device_class has been removed,
and apparently v4l-experimental still makes use of it.

I use the experimental branch on debian sid for an avermedia E506R
(hybrid cardbus analog+dvb-t)

Does anyone know a workaround ?

Here is what I get when running make:

/usr/src/v4l-dvb-experimental/v4l# make
perl scripts/make_config_compat.pl /lib/modules/2.6.26-1-686/build
./.myconfig ./config-compat.h
