4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rafał Miłecki <ra...@milecki.pl>
commit d1fe6ad6f6bd61c84788d3a7b11e459a439c6169 upstream.
Driver can report IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160MHZ so it's
important to provide valid & complete info about supported bands for
each channel. By default no support for 160 MHz should be assumed unless
firmware reports it for a given channel later.
This fixes info passed to the userspace. Without that change userspace
could try to use invalid channel and fail to start an interface.
