From 99ac64c826e62a07e5818cfde620be4d524f1edf Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Fri, 11 Dec 2009 11:58:42 +0100 Subject: [PATCH] hw-breakpoints: Handle bad modify_user_hw_breakpoint off-case return value While converting modify_user_hw_breakpoint() return value, we forgot to handle the off-case. It's not returning a pointer anymore. This solves the build warning reported by Stephen Rothwell against linux-next.
