Most devices in the driver are described as:

USB_DEVICE_AND_INTERFACE_INFO(0x0bda, 0xc82c, 0xff, 0xff, 0xff),

This particular one has:

USB_DEVICE(0x0bda, 0xc811),

When I use USB_DEVICE() instead of USB_DEVICE_AND_INTERFACE_INFO() on my
device then the Wifi driver tries to bind to the bluetooth interface on
the same device which then fails with similar error messages. Maybe you
have to use

USB_DEVICE_AND_INTERFACE_INFO(0x0bda, 0xc811, 0xff, 0xff, 0xff)

instead. I could imagine that the plain USB_DEVICE() once worked for you
because the bluetooth driver was faster to probe and only left the Wifi
interface free for the Wifi driver to probe.
