2017-07-19media: dt: bindings: Explicitly specify bus typeSakari Ailus
In the vast majority of cases the bus type is known to the driver(s) since a receiver or transmitter can only support a single one. There are cases however where different options are possible, or the bus type cannot be automatically detected. The existing V4L2 OF support tries to figure out the bus type and parse the bus parameters based on that. This does not scale too well as there are multiple serial busses that share common properties. Some hardware also supports multiple types of busses on the same interfaces.

2017-07-19Btrfs: fix dir item validation when replaying xattr deletesFilipe Manana
We were passing an incorrect slot number to the function that validates directory items when we are replaying xattr deletes from a log tree. The correct slot is stored at variable 'i' and not at 'path->slots[0]', so the call to the validation function was only correct for the first iteration of the loop, when 'i == path->slots[0]'. After this fix, the fstest generic/066 passes again.

2017-07-19workqueue: restore WQ_UNBOUND/max_active==1 to be orderedTejun Heo
The combination of WQ_UNBOUND and max_active == 1 used to imply ordered execution. After NUMA affinity 4c16bd327c74 ("workqueue: implement NUMA affinity for unbound workqueues"), this is no longer true due to per-node worker pools. While the right way to create an ordered workqueue is alloc_ordered_workqueue(), the documentation has been misleading for a long time and people do use WQ_UNBOUND and max_active == 1 for ordered workqueues which can lead to subtle bugs which are very difficult to trigger. It's unlikely that we'd see noticeable performance impact by enforcing ordering on WQ_UNBOUND / max_active == 1 workqueues. Let's automatically set __WQ_ORDERED for those workqueues.

2017-07-19libata: array underflow in ata_find_dev()Dan Carpenter
My static checker complains that "devno" can be negative, meaning that we read before the start of the loop. I've looked at the code, and I think the warning is right. This come from /proc so it's root only or it would be quite a quite a serious bug. The call tree looks like this: proc_scsi_write() <- gets id and channel from simple_strtoul() -> scsi_add_single_device() <- calls shost->transportt->user_scan() -> ata_scsi_user_scan() -> ata_find_dev() Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Tejun Heo <tj@kernel.org> Cc: stable@vger.kernel.org # all versions at this point

When this check fails, the instruction pointer should fall through to the next instruction, the ALU flags should be set to indicate VMfailValid, and the VM-instruction error should be set to 26 ("VM entry with events blocked by MOV SS").
