Subject: rtlwifi: btcoex: 21a 2ant: wifi is linking action
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f9558f5fc86b614f905e4f86aed750b433056688;p=openwrt%2Fstaging%2Fblogic.git

rtlwifi: btcoex: 21a 2ant: wifi is linking action

When wifi is under scanning/linking/roaming, do not run the reset of the
coex mechanism because these activities are important for wifi, just run
the linking process and return.
