drm/msm/a6xx: Fix a6xx indexed-regs in devcoreduump

robclark · robclark · commit 06dd5d86c6ae · 2025-03-05T16:16:19.000-08:00
Somehow, possibly as a result of rebase gone badly, setting nr_indexed_regs for pre-a650 a6xx devices lost the setting of nr_indexed_regs, resulting in values getting snapshot, but omitted from the devcoredump.
