Title:
scsi: hisi_sas: add null check before indirect pointer dereference
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Zesty:
Fix Committed
Bug description:
[Impact]
Coverity scanning discovered a potential NULL dereference in this driver.
Though I'm unaware of anyone hitting it in practice, it is an obvious bug.
[Test Case]
There is no known reproducer for this, so it can only be regression tested.
[Regression Risk]
The fix is localized to a driver and is a clean cherry pick from upstream.
The bug fix looks straightforward - don't dereference the pointer if it is
NULL. The only regression theory I have would be if this means that, instead of
crashing, we now execute code that is *worse* than crashing (e.g. resulting in
corruption, etc).
