* p2p_prepare_channel - Select operating channel for GO Negotiation
* @p2p: P2P module context from p2p_init()
* @dev: Selected peer device
* @force_freq: Forced frequency in MHz or 0 if not forced
* @pref_freq: Preferred frequency in MHz or 0 if no preference
* Returns: 0 on success, -1 on failure (channel not supported for P2P)
*
* This function is used to do initial operating channel selection for GO
* Negotiation prior to having received peer information. The selected channel
* may be further optimized in p2p_reselect_channel() once the peer information
* is available.
