wireless: don't publish __regulatory_hint
This function requires an internal lock to be held, so it cannot be published to other modules in the kernel. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

14 * __regulatory_hint - hint to the wireless core a regulatory domain
15 * @wiphy: if a driver is providing the hint this is the driver's very
16 * own &struct wiphy
17 * @alpha2: the ISO/IEC 3166 alpha2 being claimed the regulatory domain
18 * should be in. If @rd is set this should be NULL
19 * @rd: a complete regulatory domain, if passed the caller need not worry
20 * about freeing it
21 *
22 * The Wireless subsystem can use this function to hint to the wireless core
23 * what it believes should be the current regulatory domain by
24 * giving it an ISO/IEC 3166 alpha2 country code it knows its regulatory
25 * domain should be in or by providing a completely build regulatory domain.
26 *
27 * Returns -EALREADY if *a regulatory domain* has already been set. Note that
28 * this could be by another driver. It is safe for drivers to continue if
29 * -EALREADY is returned, if drivers are not capable of world roaming they
30 * should not register more channels than they support. Right now we only
31 * support listening to the first driver hint. If the driver is capable
32 * of world roaming but wants to respect its own EEPROM mappings for
33 * specific regulatory domains it should register the @reg_notifier callback
34 * on the &struct wiphy. Returns 0 if the hint went through fine or through an
35 * intersection operation. Otherwise a standard error code is returned.
