From 17d97bad1ab966f1f39b10c48cd3f858a29b3659 Mon Sep 17 00:00:00 2001 From: Markos Chandras Date: Mon, 30 Sep 2013 09:38:00 +0100 Subject: MIPS: bcm63xx: cpu: Replace BUG() with panic() BUG() can be a noop if CONFIG_BUG is not selected, leading to the following build problem on a randconfig: arch/mips/bcm63xx/cpu.c: In function 'detect_cpu_clock': arch/mips/bcm63xx/cpu.c:254:1: error: control reaches end of non-void function [-Werror=return-type] We fix this problem by replacing BUG() with panic() since it's best to handle the case of an unknown board instead of silently returning a random clock frequency.
