From be3d48106c1e5d075784e5e67928a6b5ffc0f3b6 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 24 Oct 2008 20:32:21 +0200 Subject: wireless: remove struct regdom hinting The code needs to be split out and cleaned up, so as a first step remove the capability, to add it back in a subsequent patch as a separate function. Also remove the publically facing return value of the function and the wiphy argument. A number of internal functions go from being generic helpers to just being used for alpha2 setting.
