[PATCH v10 20/25] dept: Apply timeout consideration to waitqueue wait

From: Byungchul Park
Date: Mon Jun 26 2023 - 08:20:40 EST


Now that CONFIG_DEPT_AGGRESSIVE_TIMEOUT_WAIT was introduced, apply the
consideration to waitqueue wait, assuming an input 'ret' in
___wait_event() macro is used as a timeout value.
