In drivers/net/wireless/realtek/rtlwifi/rtl8723ae/hal_btc.c, it does a global
static variable:
static struct bt_coexist_8723 hal_coex_8723;
That's not a good practice. It would be better to use the field you are removing.
To prevent wasting space, we can dynamically allocate the space when 8723AE
is presented only.
Note, I don't have this old module 8723AE, so even you achieve the patch,
I can't test it on a real hardware.
