* scsi: libsas: initialize sas_phy status according to response of DISCOVERchenxiang2018-01-091-0/+1
| | | | | | | | | | | | | | | | | | | | | The status of SAS PHY is in sas_phy->enabled. There is an issue that the status of a remote SAS PHY may be initialized incorrectly: if disable remote SAS PHY through sysfs interface (such as echo 0 > /sys/class/sas_phy/phy-1:0:0/enable), then reboot the system, and we will find the status of remote SAS PHY which is disabled before is 1 (cat /sys/class/sas_phy/phy-1:0:0/enable). But actually the status of remote SAS PHY is disabled and the device attached is not found. In SAS protocol, NEGOTIATED LOGICAL LINK RATE field of DISCOVER response is 0x1 when remote SAS PHY is disabled. So initialize sas_phy->enabled according to the value of NEGOTIATED LOGICAL LINK RATE field.

* scsi: libsas: fix error when getting phy eventsJason Yan2018-01-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | The intend purpose here was to goto out if smp_execute_task() returned error. Obviously something got screwed up. We will never get these link error statistics below: ~:/sys/class/sas_phy/phy-1:0:12 # cat invalid_dword_count 0 ~:/sys/class/sas_phy/phy-1:0:12 # cat running_disparity_error_count 0 ~:/sys/class/sas_phy/phy-1:0:12 # cat loss_of_dword_sync_count 0 ~:/sys/class/sas_phy/phy-1:0:12 # cat phy_reset_problem_count 0 Obviously we should goto error handler if smp_execute_task() returns non-zero.

* scsi: aacraid: Fix driver oops with dead batteryMeelis Roos2018-01-041-16/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The battery in my HP NetRAID-4M died of old age, and the aacraid driver started oopsing with NULL pointer dereference on startup after that.

Other subtypes of aacraid seem to have the order already correct.

| | | | | | | | | | | | | Earlier driver would scan throgh all supported buses and targets and add devices that responded. It would add devices that were _hidden_ by the fw. Driver would invalidate commands sent to _hidden_ devices via the AAC_HIDE_DISK check. Since the driver now adds only the devices that are supposed to be exposed, this code can be removed.
