      soc: apple: mailbox: error pointers are negative integers · 53ed2ac8
      Linus Torvalds authored
      In an entirely unrelated discussion where I pointed out a stupid thinko
      of mine, Rasmus piped up and noted that that obvious mistake already
      existed elsewhere in the kernel tree.
      
      An "error pointer" is the negative error value encoded as a pointer,
      making the whole "return error or valid pointer" use-case simple and
      straightforward.  We use it all over the kernel.
      
      But the key here is that errors are _negative_ error numbers, not the
      horrid UNIX user-level model of "-1 and the value of 'errno'".
      
      The Apple mailbox driver used the positive error values, and thus just
      returned invalid normal pointers instead of actual errors.
      
      Of course, the reason nobody ever noticed is that the errors presumably
      never actually happen, so this is fixing a conceptual bug rather than an
      actual one.

       "Two small fixes for tracefs and eventfs:
      
         - Fix register_snapshot_trigger() on allocation error
      
           If the snapshot fails to allocate, the register_snapshot_trigger()
           can still return success. If the call to
           tracing_alloc_snapshot_instance() returned anything but 0, it
           returned 0, but it should have been returning the error code from
           that allocation function.
      
         - Remove leftover code from tracefs doing a dentry walk on remount.
      
           The update_gid() function was called by the tracefs code on remount
           to update the gid of eventfs, but that is no longer the case, but
           that code wasn't deleted. Nothing calls it. Remove it"

       "Lots going on for rc2, ivpu has a bunch of stabilisation and debugging
        work, then amdgpu and xe are the main fixes. i915, exynos have a few,
        then some misc panel and bridge fixes.
      
        Worth mentioning are three regressions. One of the nouveau fixes in
        6.7 for a serious deadlock had side effects, so I guess we will bring
        back the deadlock until I can figure out what should be done properly.
        There was a scheduler regression vs amdgpu which was reported in a few
        places and is now fixed. There was an i915 vs simpledrm problem
        resulting in black screens, that is reverted also.
      
        I'll be working on a proper nouveau fix, it kinda looks like one of

        This is not a real solution to the issue but rather just a change to

      tracing/trigger: Fix to return error if failed to alloc snapshot · 0958b33e
      Masami Hiramatsu (Google) authored
      Fix register_snapshot_trigger() to return error code if it failed to
      allocate a snapshot instead of 0 (success). Unless that, it will register
      snapshot trigger without an error.

      platform/x86/amd/pmf: Fix memory leak in amd_pmf_get_pb_data() · a692a86e
      Cong Liu authored
      amd_pmf_get_pb_data() will allocate memory for the policy buffer,
      but does not free it if copy_from_user() fails. This leads to a memory
      leak.
