Input: Use named initializers for arrays of i2c_device_data

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

This patch doesn't modify the compiled arrays, only their representation

Input: ims-pcu - fix heap-buffer-overflow in ims_pcu_process_data()

The `ims_pcu_process_data()` processes incoming URB data byte by byte.
However, it fails to check if the `read_pos` index exceeds
IMS_PCU_BUF_SIZE.

If a malicious USB device sends a packet larger than IMS_PCU_BUF_SIZE,
`read_pos` will increment indefinitely. Moreover, since `read_pos` is
located immediately after `read_buf`, the attacker can overwrite
`read_pos` itself to arbitrarily control the index.

This manipulated `read_pos` is subsequently used in
`ims_pcu_handle_response()` to copy data into `cmd_buf`, leading to a
heap buffer overflow.

Specifically, an attacker can overwrite the `cmd_done.wait.head` located
at offset 136 relative to `cmd_buf` in the `ims_pcu_handle_response()`.
Consequently, when the driver calls `complete(&pcu->cmd_done)`, it
triggers a control flow hijack by using the manipulated pointer.

Fix this by adding a bounds check for `read_pos` before writing to
`read_buf`. If the packet is too long, discard it, log a warning,
and reset the parser state.

Merge tag 'trace-v7.0-rc4' of git://git./linux/kernel/git/trace/linux-trace

Pull tracing fixes from Steven Rostedt:

 - Revert "tracing: Remove pid in task_rename tracing output"

   A change was made to remove the pid field from the task_rename event
   because it was thought that it was always done for the current task
   and recording the pid would be redundant. This turned out to be
   incorrect and there are a few corner case where this is not true and
   caused some regressions in tooling.

 - Fix the reading from user space for migration

   The reading of user space uses a seq lock type of logic where it uses
   a per-cpu temporary buffer and disables migration, then enables
   preemption, does the copy from user space, disables preemption,
   enables migration and checks if there was any schedule switches while
   preemption was enabled. If there was a context switch, then it is
   considered that the per-cpu buffer could be corrupted and it tries
   again. There's a protection check that tests if it takes a hundred
   tries, it issues a warning and exits out to prevent a live lock.

   This was triggered because the task was selected by the load balancer
   to be migrated to another CPU, every time preemption is enabled the
   migration task would schedule in try to migrate the task but can't
   because migration is disabled and let it run again. This caused the
   scheduler to schedule out the task every time it enabled preemption
   and made the loop never exit (until the 100 iteration test
   triggered).

   Fix this by enabling and disabling preemption and keeping migration
   enabled if the reading from user space needs to be done again. This
   will let the migration thread migrate the task and the copy from user
   space will likely pass on the next iteration.

 - Fix trace_marker copy option freeing

   The "copy_trace_marker" option allows a tracing instance to get a
   copy of a write to the trace_marker file of the top level instance.
   This is managed by a link list protected by RCU. When an instance is
   removed, a check is made if the option is set, and if so
   synchronized_rcu() is called.

   The problem is that an iteration is made to reset all the flags to
   what they were when the instance was created (to perform clean ups)
   was done before the check of the copy_trace_marker option and that
   option was cleared, so the synchronize_rcu() was never called.

   Move the clearing of all the flags after the check of
   copy_trace_marker to do synchronize_rcu() so that the option is still
   set if it was before and the synchronization is performed.

 - Fix entries setting when validating the persistent ring buffer

   When validating the persistent ring buffer on boot up, the number of
   events per sub-buffer is added to the sub-buffer meta page. The
   validator was updating cpu_buffer->head_page (the first sub-buffer of
   the per-cpu buffer) and not the "head_page" variable that was
   iterating the sub-buffers. This was causing the first sub-buffer to
   be assigned the entries for each sub-buffer and not the sub-buffer
   that was supposed to be updated.

 - Use "hash" value to update the direct callers

   When updating the ftrace direct callers, it assigned a temporary
   callback to all the callback functions of the ftrace ops and not just
   the functions represented by the passed in hash. This causes an
   unnecessary slow down of the functions of the ftrace_ops that is not
   being modified. Only update the functions that are going to be
   modified to call the ftrace loop function so that the update can be
   made on those functions.

 - Do not use driver_override as IRQ name in the hwmon axi-fan driver

 - Remove an unnecessary driver_override check in sh platform_early

 - Migrate the platform bus to use the generic driver_override
   infrastructure, fixing a UAF condition caused by accessing the
   driver_override field without proper locking in the platform_match()
   callback
