From 9f547425fd9fbcb42b177ec7eec46bd4d7d4ae45 Mon Sep 17 00:00:00 2001 From: Benjamin Gaignard Date: Fri, 6 Jan 2017 10:15:03 +0100 Subject: [PATCH] drm: crc: Call wake_up_interruptible() each time there is a new CRC entry Each time new data has being added in CRC list inform reader by calling wake_up_interruptible(). This should avoid to do it in all drivers.
