Subject: [PATCH] wifi: rtlwifi: rtl8192de: Fix 5 GHz TX power
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit

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 2.4 GHz
and 5 GHz 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.
