Michal Nazarewicz 84acfd4340 spi: omap-100k: remove pointless _remove function
Commit [8074cf06: use devm_spi_register_master()] removed the last
bit of omap1_spi100k_remove function that had side effects.  After
call to spi_unregister_master was removed, the function consisted
of:

2. call to platform_get_drvdata whose return value was only used in:
2. call to spi_master_get_devdata whose return value was not used,
3. an if statement checking if zero was not zero, and
4. call to platform_get_resource whose return value was not used.

Ah, yes, and of course, final return 0. ;)

Since omap1_spi100k_remove no longer does anything, it can be
safely removed.

Grant Likely 2deff8d602 spi: Remove erroneous __init, __exit and __exit_p() references in drivers
Some of the spi driver module remove hooks were annotated with __exit
and referenced with __exit_p(). Presumably these were supposed to be
__devinit, __devexit and __devexit_p() since __init/__exit for a
probe/remove hook has never been correct. They also got missed during
the big __devinit/__devexit purge since they didn't match the pattern.
Remove then now to be rid of it.

v2: purge __init also

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.

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
