Urgent power management fix for v4.14
This fixes new breakage introduced by the most recent PM QoS fix in which, embarrassingly enough, I forgot to update dev_pm_qos_raw_read_value() to return the right default for devices with no PM QoS constraints at all which prevents runtime PM from suspending those devices (fix from Tero Kristo). -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJZ97EwAAoJEILEb/54YlRxAw8P/Rtl4qgVBGncDCDlmVK7uyaa nFGSSAdgTVo+WlyZ/ubs1zXj8ra8AhkKIOa3rwtFI21e/DejlqTxBbUHQMqSDPZC JUfS6F4hkLW86BmAMeDh+tma0oG5abXvhzx1F26/1LRFsAAORW2MQ02GUzQfe04j iThjk1J+CmfdZ5Lkc6fIWnI5bQRo7WxuYlT1GfthJVPyorTgCviQ/p5I7012HgF1 ZDwCbUWyEereybIMYaXkwXdyP2RltBKDlxRRWe/tC6O3m3VsDHWuO9+HoS6ZFMCH sicgpovEHhZagJSWdNuEK2HAvE3XoDTtWU3xSRkZpxJSarKxPD/aXZzwGkyg1x6N 8/KmuwsBuNThQLY6ODDxBP9+1ThpbpgtFbx8JMPy5/Usdm/HlIJSHZyeGSc6BWoj TI8GLEzqhF61aHWM1u5Nxh8v1DsGvAXEXLWKgQlgfInUPaw1PxYv5lCa5r4fhRzr te3ePtbaMh2bNu0fbJyYgTcteaOz/1DPSc/keYFhhGj/iU39232IzryDZKTbz0Cn Zb0OVhkpQcr+1e3HPf1aTjHVQcWds4QtTmDmaoushxmBxhdBYnWX8qiwwmSnvW8S +kkax7UY4EE7FH+8+3cW7OfqQ7vGLqqG+l3pQptf5yeGMb/hwdWidC669Be6g9Bz tZ0sDywMg2MGcbeRPx/j =xbGZ -----END PGP SIGNATURE----- Merge tag 'pm-urgent-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management fix from Rafael Wysocki: "This fixes new breakage introduced by the most recent PM QoS fix in which, embarrassingly enough, I forgot to update dev_pm_qos_raw_read_value() to return the right default for devices with no PM QoS constraints at all which prevents runtime PM from suspending those devices (fix from Tero Kristo)" * tag 'pm-urgent-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM / QoS: Fix default runtime_pm device resume latency
