Merge tag 'asoc-fix-v4.12-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

ASoC: Fixes for v4.12

This is the usual collection of device specific fixes, all accumilated
since the merge window, plus one fix from Takashi for a nasty use after
free bug that bit some things with deferred probe and an update to the
maintainer address for the former Wolfson parts.

Hi6220 SoC ION
===================================================================
Required properties:
- compatible : "hisilicon,hi6220-ion"
- list of the ION heaps
- heap name : maybe heap_sys_user@0
- heap id : id should be unique in the system.
- heap base : base ddr address of the heap,0 means that
it is dynamic.
- heap size : memory size and 0 means it is dynamic.
- heap type : the heap type of the heap, please also
see the define in ion.h(drivers/staging/android/uapi/ion.h)
-------------------------------------------------------------------
Example:
hi6220-ion {
compatible = "hisilicon,hi6220-ion";
heap_sys_user@0 {
heap-name = "sys_user";
heap-id = <0x0>;
heap-base = <0x0>;
heap-size = <0x0>;
heap-type = "ion_system";
};
heap_sys_contig@0 {
heap-name = "sys_contig";
heap-id = <0x1>;
heap-base = <0x0>;
heap-size = <0x0>;
heap-type = "ion_system_contig";
};
};
