Merge branch 'master' into driver-core-next-test-merge-rc2

Browse source 
da9846ae15 ("kernfs: make kernfs_deactivate() honor KERNFS_LOCKDEP
flag") in driver-core-linus conflicts with kernfs_drain() updates in
driver-core-next.  The former just adds the missing KERNFS_LOCKDEP
checks which are already handled by kernfs_lockdep() checks in
driver-core-next.  The conflict can be resolved by taking code from
driver-core-next.

TI-NSPIRE interrupt controller
Required properties:
- compatible: Compatible property value should be "lsi,zevio-intc".
- reg: Physical base address of the controller and length of memory mapped
region.
- interrupt-controller : Identifies the node as an interrupt controller
Example:
interrupt-controller {
compatible = "lsi,zevio-intc";
interrupt-controller;
reg = <0xDC000000 0x1000>;
#interrupt-cells = <1>;
