Revert "PM: sleep: Do not assume that "mem" is always present"
Revert commit bfcc1e67ff1e ("PM: sleep: Do not assume that "mem" is always present"), because it breaks compatibility with user space utilities assuming that "mem" will always be present in /sys/power/state. Fixes: bfcc1e67ff1e ("PM: sleep: Do not assume that "mem" is always present") Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
