Merge tag 'samsung-fixes-4.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into fixes
Pull "ARM: exynos: Fixes for v4.8, secound round" from Krzysztof Kozłowski: 1. A recent change in populating irqchip devices from Device Tree broke Suspend to RAM on Exynos boards due to lack of probing of PMU (Power Management Unit) driver. Multiple drivers attach to the PMU's DT node: irqchip, clock controller and PMU platform driver for handling suspend. The new irqchip code marked the PMU's DT node as OF_POPULATED but we need to attach to this node also PMU platform driver. 2. Add Javier as additional reviewer for Exynos patches. * tag 'samsung-fixes-4.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: ARM: EXYNOS: Clear OF_POPULATED flag from PMU node in IRQ init callback MAINTAINERS: Add myself as reviewer for Samsung Exynos support
