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.

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.
