From 0ecfacb4c50ae2fd32ee1898562fe55f045b56d2 Mon Sep 17 00:00:00 2001 From: Juerg Haefliger Date: Wed, 25 May 2022 15:32:03 +0200 Subject: [PATCH] x86/Kconfig: Fix indentation of arch/x86/Kconfig.debug The convention for indentation seems to be a single tab. Help text is further indented by an additional two whitespaces. Fix the lines that violate these rules.
