PM / Hibernate: Fix ioctl SNAPSHOT_S2RAM
The SNAPSHOT_S2RAM ioctl used for implementing the feature allowing one to suspend to RAM after creating a hibernation image is currently broken, because it doesn't clear the "ready" flag in the struct snapshot_data object handled by it. As a result, the SNAPSHOT_UNFREEZE doesn't work correctly after SNAPSHOT_S2RAM has returned and the user space hibernate task cannot thaw the other processes as appropriate. Make SNAPSHOT_S2RAM clear data->ready to fix this problem. Tested-by: Alexandre Felipe Muller de Souza <alexandrefm@mandriva.com.br> Signed-off-by: Rafael J.
