Subject: [PATCH 14/16] drm/msm: avoid using 'timespec'
Date: Fri, 8 Nov 2019 22:32:52 +0100 [thread overview]
Message-ID: <20191108213257.3097633-15-arnd@arndb.de> (raw)
In-Reply-To: <20191108213257.3097633-1-arnd@arndb.de>
The timespec structure and associated interfaces are deprecated and will
be removed in the future because of the y2038 overflow.
The use of ktime_to_timespec() in timeout_to_jiffies() does not
suffer from that overflow, but is easy to avoid by just converting
the ktime_t into jiffies directly.
