   - Visible to menuconfig; simple-mfd-i2c
   - Clean-up or clarify code; max77686, intel_soc_pmic_crc
   - Improve error handling; mc13xxx-core, stmfx, asic3
   - Pass device information to child devices; iqs62x, intel-lpss-acpi
   - Individually identify IRQ domains; intel_soc_pmic_core
   - Remove superfluous code; dbx500-prcmu, exynos-lpass
   - Staticify and constify; arizona-i2c
   - Mark sometimes used data as __maybe_unused; atmel-flexcom
   - Account for different ACPI tables on AOSP/Windows platforms; arizona-spi
