Wolfram Sang 14ac00e033 spi: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

Himangi Saraogi e9d42d1527 spi/spi-sh: Use devm_ioremap
This patch introduces the use of devm_ioremap and removes the iounmaps
in the probe and remove functions. Also, the labels are renamed to
preserve ordering.

Axel Lin 0a6d38795a spi: Always check complete callback before calling it
Since commit 1e25cd4729 "spi: Do not require a completion", this checking is
required to prevent NULL pointer dereference.

Axel Lin 23061f1eb8 spi: Remove duplicate code to set default bits_per_word setting
The implementation in spi_setup() already set spi->bits_per_word = 8 when
spi->bits_per_word is 0 before calling spi->master->setup.
So we don't need to do it again in setup() callback.

Jingoo Han 24b5a82cf5 spi: use platform_{get,set}_drvdata()
Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

Grant Likely fd4a319bc9 spi: Remove HOTPLUG section attributes
CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

Bill Pemberton has done most of the legwork on this series. I've used
his script to purge the attributes from the drivers/gpio tree.

Shimoda, Yoshihiro 0eb8880fac spi/spi-sh: add IORESOURCE_MEM_TYPE_MASK decoding for access size
This SPI controller's access size is 32, or 8-bit. The previous driver
supported 32-bit only. So, this patch adds IORESOURCE_MEM_TYPE_MASK
decoding, an then, the driver can handle the SPI controller of 8-bit.

Grant Likely 940ab88962 drivercore: Add helper macro for platform_driver boilerplate
For simple modules that contain a single platform_driver without any
additional setup code then ends up being a block of duplicated
boilerplate.  This patch adds a new macro, module_platform_driver(),
which replaces the module_init()/module_exit() registrations with
template functions.

Yong Zhang 38ada214fa spi: irq: Remove IRQF_DISABLED
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler
returns with interrupts enabled (see commit [b738a50a:
genirq: Warn when handler enables interrupts]).

So now this flag is a NOOP and can be removed.

Grant Likely ca632f5566 spi: reorganize drivers
Sort the SPI makefile and enforce the naming convention spi_*.c for
spi drivers.

This change also rolls the contents of atmel_spi.h into the .c file
since there is only one user of that particular include file.

v2: - Use 'spi-' prefix instead of 'spi_' to match what seems to be
      be the predominant pattern for subsystem prefixes.
    - Clean up filenames in Kconfig and header comment blocks
