[PATCH] dmaengine: dmatest: fix timeout caused by kthread_stop

From: Jie Hai
Date: Thu Jul 20 2023 - 07:43:49 EST


The change introduced by commit a7c01fa93aeb ("signal: break
out of wait loops on kthread_stop()") causes dmatest aborts
any ongoing tests and possible failure on the tests. This patch
use wait_event_timeout instead of wait_event_freezable_timeout
to avoid interrupting ongoing tests by signal brought by
kthread_stop().
