[PATCH v3 5/5] cfg80211: remove channel_switch combination check

[Michal Kazior <michal.kazior@tieto.com>]

Make the driver responsible for making sure it is
capable of performing the switch. It might as well
accept a request but then disconnect an interface
if some requirements are not met.

In that case userspace should be prepared for an
appropriate event (AP/IBSS/mesh being stopped/left).
