That is what v3 already does, so nothing changes there. All four are
reached from sdio.c only.

Let me list them all so you can rule on all of them at once rather than
a file at a time.

Two go regardless of your answer: the chip test inside
rtw8723bs_apply_basic_rates() and rtw8723bs_apply_bss_cap() is
redundant, both callers already establish the chip. In the second one
the NL80211_IFTYPE_STATION half of the same guard is still needed, so
only the chip half goes there.

That leaves the following outside sdio.c.

coex.c, 2 sites:

  rtw_coex_scan_notify()    -> rtw_coex_8723bs_scan_notify()
  rtw_coex_connect_notify() -> rtw_coex_8723bs_connect_notify()

  Each tests the chip and bt_disabled once and returns true when it has
  handled the notification; everything below them assumes both.

mac80211.c, 6 sites in rtw_ops_bss_info_changed(): the receive filter
on assoc and on disassoc, BSSID change bookkeeping, and the
BSS_CHANGED_ERP_PREAMBLE and BSS_CHANGED_ERP_SLOT handlers.

mac80211.c, 2 sites in rtw_ops_set_key(): enabling and disabling
default key search for group keys.

rx.c, 1 site in rtw_rx_fill_rx_status(), the zero length packet test.
This one runs per received frame, so an indirect call there looks like
the wrong trade to me. I would keep it inline unless you disagree.

fw.c, 1 site in rtw_fw_write_data_rsvd_page(), two register
save/restore blocks interleaved with the generic ones. I do not see how
to lift those into an op without restructuring the whole function, so I
would keep that inline too.

For coex.c and the two mac80211.c callbacks I am happy to add ops. One
constraint on coex.c: the 8723BS code calls rtw_coex_set_ant_path() and
rtw_coex_set_table(), which are static in coex.c. Implementing the ops
in rtw8723b.c would mean making those two non-static, which seems worse
than the chip test it replaces. What I had in mind is leaving the
functions in coex.c, declaring them in coex.h, and having rtw8723b.c
point the ops at them, the same shape as the chip_ops::prepare_tx that
v3 adds for the association sequence. The generic helpers stay static
that way.

Tell me which of those you want as ops and I will do it.

The comment on mod_delayed_work() is already in v3.
