[PATCH] fbdev/pxafb: Fix multiple clamped values in pxafb_adjust_timing
From: Thorsten Blum <hidden>
Date: 2025-12-02 18:17:12
Also in:
dri-devel, lkml, stable
Subsystem:
framebuffer layer, the rest · Maintainers:
Helge Deller, Linus Torvalds
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().
