It's good to try to make title's unique, so maybe something like this:
rtw88: make rtw8822b_hw_spec static

This should be static const to make sure it's not modified.

As Kalle's recommendation, this should be 'const'
> .ops = &rtw8822b_ops,
> .id = RTW_CHIP_TYPE_8822B,
> .fw_name = "rtw88/rtw8822b_fw.bin",
I do grep with 'rtw8822b_hw_spec':
rtw8822b.c:struct rtw_chip_info rtw8822b_hw_spec = {
rtw8822b.c:EXPORT_SYMBOL(rtw8822b_hw_spec);
rtw8822be.c: .driver_data = (kernel_ulong_t)&rtw8822b_hw_spec
rtw8822be.h:extern struct rtw_chip_info rtw8822b_hw_spec;
Making rtw8822b_hw_spec static can avoid sparse warning, but I worry that it can't
be loaded, because it is an "external" symbol and used by rtw8822be.ko.
Spuriously, it works.
However, I think we should correct them by moving extern prototype to rtw8822b.h and
include rtw8822b.h by rtw8822be.c.
