Different channels have different TX power settings. rtl8192de is using the TX power setting from the wrong channel in the 5 GHz band because _rtl92c_phy_get_rightchnlplace expects an array which includes all the channel numbers, but it's using an array which includes only the 5 GHz channel numbers. Use the array channel_all (defined in rtl8192de/phy.c) instead of the incorrect channel5g (defined in core.c). Tested only with rtl8192du, which will use the same TX power code.
