At the beginning of wiphy_update_regulatory() a check is performed whether the request is to be ignored. Then the request is sent to the driver nevertheless. This happens even if last_request points to NULL, leading to a crash in the driver: [<bf01d864>] (lbs_set_11d_domain_info+0x28/0x1e4 [libertas]) from [<c03b714c>] (wiphy_update_regulatory+0x4d0/0x4f4) [<c03b714c>] (wiphy_update_regulatory+0x4d0/0x4f4) from [<c03b4008>] (wiphy_register+0x354/0x420) [<c03b4008>] (wiphy_register+0x354/0x420) from [<bf01b17c>] (lbs_cfg_register+0x80/0x164 [libertas]) [<bf01b17c>] (lbs_cfg_register+0x80/0x164 [libertas]) from [<bf020e64>] (lbs_start_card+0x20/0x88 [libertas]) [<bf020e64>] (lbs_start_card+0x20/0x88 [libertas]) from [<bf02cbd8>] (if_sdio_probe+0x898/0x9c0 [libertas_sdio]) Fix this by returning early. Also remove the out: label as it is not any longer needed.
