    PM: Add sysfs attr for rechecking dev hash from PM trace · d33ac60b
    James Hogan authored
    If the device which fails to resume is part of a loadable kernel module
    it won't be checked at startup against the magic number stored in the
    RTC.
    
    Add a read-only sysfs attribute /sys/power/pm_trace_dev_match which
    contains a list of newline separated devices (usually just the one)
    which currently match the last magic number. This allows the device
    which is failing to resume to be found after the modules are loaded
    again.
