This patch series fixes an issue when do discovery on an empty PHY to update PHY info after device unregister could cause newly connected device to not be scanned. Changes since v2: - Based on John's suggestion, allow smp_execute_task() arguments to be on the stack. - Based on John's suggestion, add a helper sas_get_sas_addr_and_dev_type. - Updated comments. Changes since v1: - Use sas_get_phy_discover() instead of sas_get_phy_attached_dev() in sas_rediscover_dev() and use disc_resp to update phy info.
