[PATCH 15/42] ACPI / PM: acpi_hibernation_enter() need not switch interrupts off

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Rafael J. Wysocki <rjw@xxxxxxx>

The function acpi_hibernation_enter() is always called with
interrupts off, so it doesn't need to switch them off and on.
