Subject: [PATCH v3 1/4] rtw88: Fix sparse warning for rtw8822b_hw_spec
Date:   Tue, 24 May 2022 10:36:18 -0500

Sparse lists the following for rtw88:

  CHECK   drivers/net/wireless/realtek/rtw88/rtw8822b.c
drivers/net/wireless/realtek/rtw88/rtw8822b.c:2500:22: warning: symbol 'rtw8822b_hw_spec' was not declared. Should it be static?

The warning arises because the external declaration for rtw8822b_hw_spec
occurs in rtw8822be.h, which is not included in rtw8822b.h. That line is
moved, and the now empty file rtw8822be.h is deleted.

Symbol 'rtw8822b_hw_spec' can be made constant.

v2 Change patch subjects as recommended by Kalle
v3 Make the correct fix for the warnings - 'static' is incorrect, but const is correct
