From: "Dr. David Alan Gilbert" <linux@treblig.org>

rtl_usb_resume() and rtl_usb_suspend() are trivial stubs that were
added in 2011's
commit 2ca20f79e0d8 ("rtlwifi: Add usb driver")
but aren't wired up anywhere (though commit 442888c706e9 ("rtlwifi:
rtl8192cu: Add routines dm, fw, led and sw")  added commented
out assignments).

Remove them.

Thanks!
Did you see the question in the 0/3 cover letter asking why
rtl8188ee_bt_hw_init() isn't called?

Checked vendor driver. For RTL8188E, only USB interface implements this function,
but no caller. The PCI interface doesn't support Bluetooth.

I think you can find the vendor drivers in github or somewhere. That's not
too hard to address this.
