From 1ff5f55a8c7b011f818434923a93afc48de0b2ee Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Thu, 10 Jan 2013 21:58:38 +0800 Subject: ARM: samsung: remove unused arch_decomp_wdog() code Besides the fact that CONFIG_S3C_BOOT_WATCHDOG is defined nowhere, with ARCH_HAS_DECOMP_WDOG removed from arch/arm/boot/compressed/decompress.c, all the arch_decomp_wdog() related code is not used. Remove them.
