Will do in v9.

Two details I would rather ask about than decide on my own, since both
touch the other SDIO parts rather than this chip.

The unaligned SKB warning uses __func__, and today that resolves to
rtw_sdio_write_port on every chip. Once the generic path moves into its
own function the string becomes that function's name for 8703b, 8723d,
8821c, 8822b and 8822c. Nothing reads it, but it is still a visible
change to parts this series is not about. The options I see are to let
it change and say so in the change log, to drop __func__ and word the
message without a function name, or to keep the check in the dispatcher
so the string stays as it is.

I would take the first, since the name then simply follows whichever
function ran. The third is the only one that leaves the other parts
completely alone, but it would move the warning ahead of
rtw_sdio_check_free_txpg() on the generic path, so a page shortage would
start logging a line it does not log today. That seems worse than the
string changing. Say if you would rather have it either of the other
ways.

The chip specific helpers already use the _8723bs_ prefix, which is the
convention you asked for in v4, so I plan to keep
rtw_sdio_8723bs_write_port() and add rtw_sdio_write_port_common()
next to it. Happy to rename them to match your sketch if you would
rather they read that way.
