Subject: rtlwifi: Add modifier static to functions reported by sparse
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=91b9e6844240fc79e1155ac6fe36d2cebc292718;p=openwrt%2Fstaging%2Fblogic.git

rtlwifi: Add modifier static to functions reported by sparse

sparse reports some functions were not declared, so add 'static' as
modifier. Remove an unused function btc8821a1ant_is_wifi_status_changed()
exposed due to 'static'.
