Subject: rtw88: coex: add separate flag for manual control
X-Git-Tag: v5.11-rc1~169^2~122^2~64
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=32c3a8c7d91f1de83d570b9f0f8ceb20a7c8a270;p=tomoyo%2Ftomoyo-test1.git

rtw88: coex: add separate flag for manual control

The original stop_dm flag is shared with the wifi and coexistence
mechanism internal usage, which represent two meanings, and makes
developers hard to debug.
Add a new flag manual_control for coexistence mechanism usage only.
