[PATCH] ASoC: tegra: Fix ASRC Stream6 input threshold control
From: Sheetal
Date: Mon Oct 05 2026 - 05:00:11 EST
The Stream6 Input Threshold control points at stream index 4, which is
already used by Stream5. The threshold get and put callbacks derive the
lane ID from the register offset, so the duplicate index makes Stream6
operate on lane 4 and leaves lane 5 inaccessible from userspace.
Use stream index 5 for Stream6.

Changes from RFC v1:
- Split out from the ASRC ratio-control RFC series because this is an
independent fix and should not be blocked by the ABI discussion.
