[PATCH] ipw2200: Fix rf_kill is activated after mode change with 'disable=1'
When loading the ipw2200 module with disabled=1, rf_kill is activated after every mode change. This is caused by ipw_sw_reset() is called when a mode is changed. The patch fixed the problem by distinguishing the purposes with the 'option' paramenter. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
