Commit c31e5f9f ('sfc: Add channel specific receive_skb handler and post_remove callback') added the function pointer field efx_channel_type::post_remove and an unconditional call through it. This field should have been initialised to efx_channel_dummy_op_void in the existing instances of efx_channel_type, but this was only done in efx_default_channel_type. Consequently, if a device has SR-IOV enabled then removing the driver or device will result in an oops. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
