Subject: [PATCH 02/19] cfg80211: force WIPHY_FLAG_CUSTOM_REGULATORY on wiphy_apply_custom_regulatory()
Date: Tue, 5 Nov 2013 09:18:00 -0800 [thread overview]
Message-ID: <1383671897-7746-3-git-send-email-mcgrof@do-not-panic.com> (raw)
In-Reply-To: <1383671897-7746-1-git-send-email-mcgrof@do-not-panic.com>
wiphy_apply_custom_regulatory() implies WIPHY_FLAG_CUSTOM_REGULATORY
but we never enforced it, do that now and warn if the driver
didn't set it. All drivers should be following this today already.
Having WIPHY_FLAG_CUSTOM_REGULATORY does not however mean you will
use wiphy_apply_custom_regulatory() though, you may have your own
_orig value set up tools / helpers. The intel drivers are examples
of this type of driver.
