6.12-stable review patch. If anyone has any objections, please let me know.

From: Thorsten Blum thorsten.blum@linux.dev
commit c4cdf7376271bce5714c06d79ec67759b18910eb upstream.
The local variable 'val' was never clamped to -75000 or 180000 because the return value of clamp_val() was not used. Fix this by assigning the clamped value back to 'val', and use clamp() instead of clamp_val().
