[PATCH] x86/cpu: cleanup duplicate dependencies in Kconfig
From: Julian Braha
Date: Sun May 31 2026 - 02:58:09 EST
The Kconfig in the choice menu already has an 'if X86'
affecting all of the config options within the choice, meaning that each
of the individual 'depends on' statements in this file is a duplicate
dependency (dead code).
Let's leave the initial 'depends on X86_32' in the choice menu,
and remove the individual dependencies from each option.
This dead code was found by kconfirm, a static analysis tool for Kconfig.
