Boris Brezillon e7bfb3fdbd mtd: Stop updating erase_info->state and calling mtd_erase_callback()
MTD users are no longer checking erase_info->state to determine if the
erase operation failed or succeeded. Moreover, mtd_erase_callback() is
now a NOP.

We can safely get rid of all mtd_erase_callback() calls and all
erase_info->state assignments. While at it, get rid of the
erase_info->state field, all MTD_ERASE_XXX definitions and the
mtd_erase_callback() function.

Arnd Bergmann b0e302b408 staging: goldfish: use div64_s64 instead of do_div
The goldfish nand driver divides a signed 64-bit number (loff_t)
in multiple places using the do_div() function. This has always
been unreliable but now produces a compiler warning (since 4.5-rc1):

goldfish/goldfish_nand.c: In function 'goldfish_nand_erase':
goldfish/goldfish_nand.c:107:91: error: comparison of distinct pointer types lacks a cast [-Werror]
goldfish/goldfish_nand.c: In function 'goldfish_nand_read_oob':
goldfish/goldfish_nand.c:145:91: error: comparison of distinct pointer types lacks a cast [-Werror]

This changes the code to the equivalent div_s64{,_rem} that
works correctly for negative numbers (which we should never
get here).

The warning has shown up on ARM allmodconfig builds after the goldfish
bus driver has become visible on ARM.

Peter Senna Tschudin 07d783fd83 staging: goldfish: Fix pointer cast for 32 bits
As the first argument of gf_write64() was of type unsigned long, and as
some calls to gf_write64() were casting the first argument from void *
to u64 the compiler and/or sparse were printing warnings for casts of
wrong sizes when compiling for i386.

This patch changes the type of the first argument of gf_write64() to
const void *, and update calls to the function. This change fixed the
warnings and allowed to remove casts from 3 calls to gf_write64().

In addition gf_write64() was renamed to gf_write_ptr() as the name was
misleading because it only writes 32 bits on 32 bit systems.

gf_write_dma_addr() was added to handle dma_addr_t values which is
used at drivers/staging/goldfish/goldfish_audio.c.

Somya Anand 6e3f3bb863 Staging: goldfish: use !x instead of x == NULL
Functions like devm_kzalloc, kmalloc_array, devm_ioremap,
usb_alloc_urb, alloc_netdev return NULL as a return value on failure.
Generally, When NULL represents failure, !x is commonly used.

This patch cleans up the tests on the results of these functions, thereby
using !x instead of x == NULL or NULL == x. This is done via following
coccinelle script:
@prob_7@
identifier x;
statement S;
@@

(
 x = devm_kzalloc(...);
|
 x = usb_alloc_urb(...);
|
 x = kmalloc_array(...);
|
 x = devm_ioremap(...);
|
 x = alloc_netdev(...);
)
 ...
- if(NULL == x)
+ if(!x)
        S
Further we have used isomorphism characteristics of coccinelle to
indicate x == NULL and NULL == x are equivalent. This is done via
following iso script.

Expression
@ is_null @ expression X; @@
X == NULL <=> NULL == X

Arve Hjønnevåg 8e404fffea goldfish: NAND flash driver
Fold together the NAND driver for Goldfish from Arve with cleanups by
Jun Nakajima and a tidy up to 3.7 and checkpatch.

This provides a virtual flash driver for the Goldfish Android Virtual Platform,
and which is normally used as the root file system when testing emulated
devices.

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.
