Subject: [PATCH] rtlwifi: btcoex: make function btc8723b2ant_dac_swing static

From: Colin Ian King <colin.king@...onical.com>

The function btc8723b2ant_dac_swing  is local to the source and
does not need to be in global scope, so make it static.

Cleans up sparse warning:
symbol 'btc8723b2ant_dac_swing' was not declared. Should it be static?
