2021-08-16drm/amd/amdgpu embed hw_fence into amdgpu_jobJack Zhang
Why: Previously hw fence is alloced separately with job. It caused historical lifetime issues and corner cases. The ideal situation is to take fence to manage both job and fence's lifetime, and simplify the design of gpu-scheduler. How: We propose to embed hw_fence into amdgpu_job. 1. We cover the normal job submission by this method. 2. For ib_test, and submit without a parent job keep the legacy way to create a hw fence separately. v2: use AMDGPU_FENCE_FLAG_EMBED_IN_JOB_BIT to show that the fence is embedded in a job. v3: remove redundant variable ring in amdgpu_job v4: add tdr sequence support for this feature.

2021-08-16scsi: qedf: Fix error codes in qedf_alloc_global_queues()Dan Carpenter
This driver has some left over "return 1" on failure style code mixed with "return negative error codes" style code. The caller doesn't care so we should just convert everything to return negative error codes. Then there was a problem that there were two variables used to store error codes which just resulted in confusion. If qedf_alloc_bdq() returned a negative error code, we accidentally returned success instead of propagating the error code. So get rid of the "rc" variable and use "status" every where. Also remove the "status = 0" initialization so that these sorts of bugs will be detected by the compiler in the future.

This function had some left over code that returned 1 on error instead negative error codes. Convert everything to use negative error codes. The caller treats all non-zero returns the same so this does not affect run time. A couple places set "rc" instead of "status" so those error paths ended up returning success by mistake. Get rid of the "rc" variable and use "status" everywhere. Remove the bogus "status = 0" initialization, as a future proofing measure so the compiler will warn about uninitialized error codes.

2021-08-16block: nbd: add sanity check for first_minorPavel Skripkin
Syzbot hit WARNING in internal_create_group(). The problem was in too big disk->first_minor. disk->first_minor is initialized by value, which comes from userspace and there wasn't any sanity checks about value correctness. It can cause duplicate creation of sysfs files/links, because disk->first_minor will be passed to MKDEV() which causes truncation to byte. Since maximum minor value is 0xff, let's check if first_minor is correct minor number. NOTE: the root case of the reported warning was in wrong error handling in register_disk(), but we can avoid passing knowingly wrong values to sysfs API, because sysfs error messages can confuse users. For example: user passed 1048576 as index, but sysfs complains about duplicate creation of /dev/block/43:0. It's not obvious how 1048576 becomes 0. Log and reproducer for above example can be found on syzkaller bug report page.

2021-08-16PM: domains: Add support for 'required-opps' to set default perf stateRajendra Nayak
Some devices within power domains with performance states do not support DVFS, but still need to vote on a default/static state while they are active. They can express this using the 'required-opps' property in device tree, which points to the phandle of the OPP supported by the corresponding power-domains. Add support to parse this information from DT and then set the specified performance state during attach and drop it on detach. runtime suspend/resume callbacks already have logic to drop/set the vote as needed and should take care of dropping the default perf state vote on runtime suspend and restore it back on runtime resume.

2021-08-16opp: Don't print an error if required-opps is missingRajendra Nayak
The 'required-opps' property is considered optional, hence remove the pr_err() in of_parse_required_opp() when we find the property is missing. While at it, also fix the return value of of_get_required_opp_performance_state() when of_parse_required_opp() fails, return a -ENODEV instead of the -EINVAL.

2021-08-16Revert "media: device property: Call fwnode_graph_get_endpoint_by_id() for ↵Daniel Scally
fwnode->secondary" This reverts commit acd418bfcfc415cf5e6414b6d1c6acfec850f290. Checking for endpoints against fwnode->secondary in fwnode_graph_get_next_endpoint() is a better way to do this since that function is also used in a bunch of other places, for instance sensor drivers checking that they do have an endpoint connected during probe. This reversion depends on the previous patch in this series, "device property: Check fwnode->secondary in fwnode_graph_get_next_endpoint()".
