Subject: [PATCH] tee: optee: interruptible RPC sleep
Date: Mon, 17 Jul 2017 12:10:13 +0200	[thread overview]
Message-ID: <1500286213-29560-1-git-send-email-jens.wiklander@linaro.org> (raw)

From: tiger-yu99 <tigeryu99@hotmail.com>

Prior to this patch RPC sleep was uninterruptible since msleep() is
uninterruptible. Change to use msleep_interruptible() instead.
