rtw88: leave PS state for dynamic mechanism (37ba5de2) · Commits · 戴 / test

Dynamic mechanism requires BB/RF working to adjust hardware settings. But PS state periodically turns off BB/RF, could lead to wrong setting. So leave PS state before DM to make sure it works. And then check if we can enter PS state again. Signed-off-by:
