Hello,

when I try to rmmod the saa7134 module from kernel 2.6.0-test7, I get
this call trace:

Device class 'i2c-1' does not have a release() function, it is broken
and must be fixed.
Badness in class_dev_release at drivers/base/class.c:200
Call Trace:

And when I try to build the driver into the kernel (not as a module), I
get this link failure:

drivers/built-in.o(.text+0x89a60): In function `saa7134_initdev':
: undefined reference to `register_sound_dsp'

drivers/built-in.o(.text+0x89eb2): In function `saa7134_finidev':

make: *** [.tmp_vmlinux1] Error 1

But this has never worked.

Best regards,
Stian
