From e74b1e7fb2f12db36f25af2158ee6e2940e4f138 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Thu, 22 Jan 2009 15:05:48 -0800 Subject: [PATCH] cfg80211: ignore consecutive equal regulatory hints We ignore regulatory hints for the same alpha2 if we already have processed the same alpha2 on the current regulatory domain. For a driver regulatory_hint() this means we copy onto its wiphy->regd the previously procesed regulatory domain from CRDA without having to call CRDA again. Signed-off-by: Luis R.
