/**

 * regulatory_hint_user - hint to the wireless core a regulatory domain

 * which the driver has received from an application

 * @alpha2: the ISO/IEC 3166 alpha2 the driver claims its regulatory domain

 *	should be in. If @rd is set this should be NULL. Note that if you

 *	set this to NULL you should still set rd->alpha2 to some accepted

 *	alpha2.

 * @user_reg_hint_type: the type of user regulatory hint.

 *

 * Wireless drivers can use this function to hint to the wireless core

 * the current regulatory domain as specified by trusted applications,

 * it is the driver's responsibilty to estbalish which applications it

 * trusts.

 *

 * The wiphy should be registered to cfg80211 prior to this call.

 * For cfg80211 drivers this means you must first use wiphy_register(),

 * for mac80211 drivers you must first use ieee80211_register_hw().

 *

 * Drivers should check the return value, its possible you can get

 * an -ENOMEM or an -EINVAL.

 *

 * Return: 0 on success. -ENOMEM, -EINVAL.
