| |
This patch set is to define the positive value returned by device .prepare() callbacks, which is used to indicate the devices are OK to remain in runtime-suspended during system sleep. A precise return value would make the code more readable.
Based on this definition, optimized the suspend process in intel-lpss driver.
Chen Yu (2): PM / sleep: Return RPM_SUSPENDED to keep devices in runtime-suspended mfd: intel-lpss: Avoid resuming runtime-suspended lpss unnecessarily
