From: Johannes Berg Date: Tue, 6 Mar 2012 21:30:59 +0000 (-0800) Subject: iwlwifi: move ucode_owner to priv X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=947a9407e34e7c8d44a0f4d95bbb1e5eae5459c0;p=openwrt%2Fstaging%2Fblogic.git iwlwifi: move ucode_owner to priv The transport doesn't really need to know as we can enforce it in the command wrapper. Move the ucode_owner variable into priv and do all enforcing there. Signed-off-by: Johannes Berg Signed-off-by: Wey-Yi Guy Signed-off-by: John W.
