Subject: i386: Remove unneeded test of 'task' in dump_trace()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=028a690a1ebc8b;p=deliverable%2Flinux.git

i386: Remove unneeded test of 'task' in dump_trace()

Remove unneeded test of task != NULL from
arch/i386/kernel/traps.c::dump_trace()

At the start of the function we have this test:
        if (!task)
                task = current;
so further down there's no need to test 'task'.
