Subject[PATCH] arm: remove references on undefined CPU_S3C2413
Date
CPU_S3C2413 is not defined in Kconfig, so that all references on it turn
out to be 0. Since CPU_S3C2412 supports both, S3C2412 and S3C2413 SoCs
from the S3C24XX line, we can safely remove all dead references on
CPU_S3C2413.

I detected this issue with scripts/checkkconfigsymbols.py

A very similar patch has already been proposed by Paul Bolle [1], but
has been left unanswered.
