From 2f0993e0fb663c49e4d1e02654f6203246be4817 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Sat, 5 Dec 2009 07:06:10 +0100 Subject: hw-breakpoints: Drop callback and task parameters from modify helper Drop the callback and task parameters from modify_user_hw_breakpoint(). For now we have no user that need to modify a breakpoint to the point of changing its handler or its task context. Signed-off-by: Frederic Weisbecker Cc: "K.
