cfg80211: replace reg.c Nokia commit c4c32294
Nokia hasn't gotten back to me in over 1 month for a relicense change request. There are only a few changes that they contributed, so just reverting their changes but replacing with another set. This change replaces this commit: commit c4c322941ce0d7e2b7b8794ad70683123d9cb26a Author: Yuri Ershov <ext-yuri.ershov@nokia.com> Date: Tue Jun 29 15:08:08 2010 +0400 cfg80211: Update of regulatory request initiator handling In some cases there could be possible dereferencing freed pointer. The update is intended to avoid this issue. Signed-off-by: Yuri Ershov <ext-yuri.ershov@nokia.com> Signed-off-by: John W. Linville <linville@tuxdriver.com> Cc: Petri Karhula <petri.karhula@nokia.com> Signed-off-by: Luis R. Rodriguez <mcgrof@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
