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

From: Thorsten Blum thorsten.blum@linux.dev
commit 0155e868cbc111846cc2809c1546ea53810a56ae upstream.
The variables were never clamped because the return value of clamp_val() was not used. Fix this by assigning the clamped values, and use clamp() instead of clamp_val().
