  "message": "PM: introduce set_target method in pm_ops\n\nCommit 52ade9b3b97fd3bea42842a056fe0786c28d0555 changed the suspend code\nordering to execute pm_ops-\u003eprepare() after the device model per-device\n.suspend() calls in order to fix some ACPI-related issues.  Unfortunately, it\nbroke the at91 platform which assumed that pm_ops-\u003eprepare() would be called\nbefore suspending devices.\n\nat91 used pm_ops-\u003eprepare() to get notified of the target system sleep state,\nso that it could use this information while suspending devices.  However, with\nthe current suspend code ordering pm_ops-\u003eprepare() is called too late for\nthis purpose.  Thus, at91 needs an additional method in \u0027struct pm_ops\u0027 that\nwill be used for notifying the platform of the target system sleep state.\nMoreover, in the future such a method will also be needed by ACPI.\n\nThis patch adds the .set_target() method to \u0027struct pm_ops\u0027 and makes the\nsuspend code call it, if implemented, before executing the device model\nper-device .suspend() calls.  It also modifies the at91 code to use\npm_ops-\u003eset_target() instead of pm_ops-\u003eprepare().\n\nSigned-off-by: Rafael J.
