[PATCH v2 07/10] staging: rtl8723bs: remove dead code

From: Arnd Bergmann
Date: Wed Oct 11 2023 - 10:03:47 EST

From: Arnd Bergmann <arnd@xxxxxxxx>

The .ndo_do_ioctl functions are never called, so the three implementation here
is useless but only works as a way to identify the device in the notifiers,
which can really be removed as well.

Looking through the exported functions, I found a bunch more that have
no callers, so just drop all of those.
