Hi there,
I am trying to also add support for for using SI2165 driver on HVR4400
and HVR5500 cards.
The pci subdevice id of the HVR5500 (0x0070:0xc138) is assigned to
HVR4400 in cx23885-cards.c.
Is that just because the DVB-S2 part is identical, to not add redundant
code? In this case I could jus

This is required so that we give up the last reference to the device.
Remove the kfree() because the put_device() call will actually call
release_sub_device which in turn kfrees the device.
