NACK. Whenever Sparse issues this warning, you should first check to see if it
can be made static. Adding it to a header to make the Sparse warning go away is
not correct unless some other routine needs it to be globally known. In this
case, no other routine needs it.
Of course, making it static will lead to the compilation warning that the
routine is not used. The correct patch is to delete the entire routine as it is
never called.

This function is never used in current linux-next. So I think it might
as well be dropped.
Note there's also Efuse_GetCurrentSize23a (with an uppercase 'E'). It's
used just once. You could probably submit another patch to remove that
from rtw_efuse.h and make it static in rtw_efuse.c The comment above
that function needs and update too, but maybe it's also OK to drop that
comment.

Yep, fix it correctly, or don't bother!

Fix sparse warning:
drivers/staging/rtl8723au/core/rtw_efuse.c:579:5: warning: symbol 'efuse_GetCurrentSize23a' was not declared. Should it be static?
by removing efuse_GetCurrentSize23a since its never used
