accel/rocket: fix unwinding in error path in rocket_probe

When rocket_core_init() fails (as could be the case with EPROBE_DEFER),
we need to properly unwind by decrementing the counter we just
incremented and if this is the first core we failed to probe, remove the
rocket DRM device with rocket_device_fini() as well. This matches the
logic in rocket_remove(). Failing to properly unwind results in
out-of-bounds accesses.

iommu_group pointer NULL. This aligns with what's done in

drm/i915/cdclk: Incorporate Xe3_LPD changes for CD2X divider

On Xe3_LPD, there is no instruction to program the CD2X divider anymore
and the hardware is expected to always use the default value of 0b00,
meaning "divide by 1".

With that, the CDCLK_CTL register was changed so that:

  (1) The field "CD2X Divider Select" became a debug-only field.
      Because we are programming CDCLK_CTL with a direct write instead
      of read-modify-write operation, we still need to program "CD2X
      Divider Select" in order to keep the field from deviating from its
      default value.  Let's, however, throw a warning if we encounter a
      CDCLK value that would result in an unexpected value for that
      field.

  (2) The field "CD2X Pipe Select" has been removed. In fact, some
      debugging in a PTL machine showed that such field comes back as
      zero after writing a non-zero value to it.  As such, do not
      program it starting with Xe3_LPD.

2 months agomei: late_bind: fix struct intel_lb_component_ops kernel-doc
Jani Nikula [Wed, 7 Jan 2026 16:02:26 +0000 (18:02 +0200)]
mei: late_bind: fix struct intel_lb_component_ops kernel-doc

Fix kernel-doc warnings on struct intel_lb_component_ops:

Warning: include/drm/intel/intel_lb_mei_interface.h:55 Incorrect use of
  kernel-doc format: * push_payload - Sends a payload to the
  authentication firmware

And a bunch more. There isn't really support for documenting function
pointer struct members in kernel-doc, but at least reference the member
properly.

Fixes: 741eeabb7c78 ("mei: late_bind: add late binding component driver")
