Subject: [PATCH v3 0/3] rtc: tps6594: Add power management support

This series add power management support for tps6594_rtc.

The 1st patch fixes a memleak found in the probe()
The 2nd patch simply introduce a private structure as drvdata that will
be used in the 3rd patch. (no functionnal change)
The 3rd patch introduce the power management support.

Changes in v3:
 - Fix a memleak found in probe()
 - introduce a private structure to prevent squatting the mfd structure
   (struct tps6594) with rtc-only related stuff.

Changes in v2:
 - use DEFINE_SIMPLE_DEV_PM_OPS instead of deprecated SIMPLE_DEV_PM_OPS
   (This fixes the defined but unsed warning when CONFIG_PM is unset)
