The ISR_HPD_* enum should represent values that can be read from the

ISR_HPD_REPLUG_COUNT to map them correctly to register values.
While we are at it, correct the spelling for ISR_HPD_REPLUG_COUNT.

drm/msm: Don't use UTS_RELEASE directly
...
UTS_RELEASE evaluates to a static string and changes quite easily (e.g.
uncommitted changes in the source tree or new commits). So when checking
if a patch introduces changes to the resulting binary each usage of
UTS_RELEASE is source of annoyance.
Instead of using UTS_RELEASE directly use init_utsname()->release which
evaluates to the same string but with that a change of UTS_RELEASE
doesn't affect msm_disp_snapshot_util.o or msm_gpu.o.

drm/msm/dsi: don't dump registers past the mapped region

On DSI 6G platforms the IO address space is internally adjusted by
io_offset. Later this adjusted address might be used for memory dumping.
However the size that is used for memory dumping isn't adjusted to
account for the io_offset, leading to the potential access to the
unmapped region. Lower ctrl_size by the io_offset value to prevent
access past the mapped area.

drm/msm/dpu: Fix Kaanapali CWB register configuration

The Kaanapali DPU catalog defines kaanapali_cwb[] with the correct
CWB base addresses for this platform (0x169200, 0x169600, 0x16a200,
0x16a600), but the dpu_kaanapali_cfg struct was mistakenly pointing
to sm8650_cwb instead. The SM8650 CWB blocks sit at completely
different offsets (0x66200, 0x66600, 0x7E200, 0x7E600), so using
them on Kaanapali would program CWB registers at wrong addresses,
corrupting unrelated hardware blocks and breaking writeback capture.
Fix this by pointing .cwb to the correct kaanapali_cwb array.

Commit 3bce3fdd1f ("drm: rcar-du: Don't leak device_link to CMM")
refactored CMM handling, and introduced an incorrect test for CMM
availability. When no CMM is present, the rcrtc->cmm field is NULL,
testing rcrtc->cmm->dev causes a NULL pointer dereference. This slipped
through testing as all tests were run with the CMM present.
Fix this issue by correctly testing for rcrtc->cmm.
