[PATCH 0/2] Define positive return value to RPM_SUSPEND for runtime-suspended devices

[Chen Yu <yu.c.chen@intel.com>]

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.

  PM / sleep: Return RPM_SUSPENDED to keep devices in runtime-suspended
  mfd: intel-lpss: Avoid resuming runtime-suspended lpss unnecessarily
