Himangi Saraogi 85f28332e3 staging: goldfish: Introduce the use of managed interfaces
This patch introduces the use of managed interfaces like devm_kzalloc,
devm_ioremap, dmam_alloc_coherent, devm_request_irq and does away with
the calls to functions to free the allocated memory in the probe and
remove functions. Also, the labels are removed in the probe function.

Hoang Tran 92271551b6 staging: goldfish: fix coding style.
Using an else following a break or return can unnecessarily
indent code blocks.

This patch fixes coding style reported by checkpatch.pl, a part
of eudyptula challenge.

Nick Kralevich ec5e34c074 goldfish_nand.c: remove length restrictions
Remove limitations on the size of a read / write request.
AFAIK, there's no consequence to allowing the upper layers
to specify different read / write sizes.

This is needed to support running ext4 on goldfish.

Paul Gortmaker 885a947e5b staging: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

Alan Cox 2e82b83dc3 goldfish: audio support
(remove change to another file that escaped into the patch set)

From: Mike Lockwood <lockwood@google.com>

Provide a simple audio channel between the kernel and the emulator that host
sit. Queued for staging right now as this ought to be an ALSA driver not
just a dumb device of its own making.
