Subject: dmaengine: dmatest: correct thread_count while using multiple thread per channel
From: Nicolas Ferre <nicolas.ferre@xxxxxxxxx>
It seems that thread_count is not properly calculated in dmatest. In fact
the thread count number that is returned from dmatest_add_threads() is not
correctly added to the thread_count and thus not properly printed.
