[PATCH 24/27] tracing: Remove use of seq_printf return value

From: Joe Perches
Date: Sat Feb 21 2015 - 21:56:44 EST

The seq_printf return value, because it's frequently misused,
will eventually be converted to void.

See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
seq_has_overflowed() and make public")


o Remove unused return value from trace_lookup_stack
