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

From: Arnd Bergmann <[email-masked]>
Date: Mon, 9 Oct 2023 16:19:05 +0200

From: Arnd Bergmann <[email-masked]>

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.
