   - Ensure fault log is cleared (da9052)
   - Remove NO_IRQ check (ucb1x00-core)
   - Supply I2C properties (intel-lpss-acpi, intel-lpss-pci)
   - Non standard declaration (tps65217, max8997-irq)
   - Remove unused code (lp873x, db8500-prcmu, ab8500-debugfs,
     cros_ec_spi)
   - Make non-modular (altera-a10sr, intel_msic, smsc-ece1099,
     sun6i-prcm, twl-core)
   - OF bindings (ac100, stmpe, qcom-pm8xxx, qcom-rpm, rk808, axp20x,
     lp873x, exynos5433-lpass, act8945a, aspeed-scu, twl6040, arizona)

  Bugfixes:
   - Release OF pointer (qcom_rpm)
   - Avoid double shifting in suspend/resume (88pm80x)
   - Fix 'defined but not used' error (exynos-lpass)
   - Fix 'sleeping whilst attomic' (atmel-hlcdc)"
