200_gpio driver is working, we copy and
modify the function and variable names, and rework the access-method bodies
for the different addressing scheme.

Heres a working overview of the patchset:

# series file for GPIO

# Spring Cleaning
gpio-scx/patch.preclean        # scripts/Lindent fixes, editor-ctrl comments

# API Modernization

gpio-scx/patch.api26        # what I learned from LDD3
gpio-scx/patch.platform-dev-2    # get pdev, support for dev_dbg()
gpio-scx/patch.unsigned-minor    # fix to match std practice

# Debuggability

gpio-scx/patch.dump-diet    # shrink gpio_dump()
gpio-scx/patch.viewpins        # add new 'command' to call dump()
gpio-scx/patch.init-refactor    # pull shadow-register init to sub

# Access-Abstraction (add vtable)

gpio-scx/patch.access-vtable    # introduce nsg_gpio_ops vtable, w dump
gpio-scx/patch.vtable-calls    # add & use the vtable in scx200_gpio
gpio-scx/patch.nscgpio-shell    # add empty driver for common-fops

# move code under abstraction
gpio-scx/patch.migrate-fops    # move file-ops methods from scx200_gpio
gpio-scx/patch.common-dump    # mv scx200.c:scx200_gpio_dump() to nsc_gpio.c
gpio-scx/patch.add-pc8736x-gpio    # add new driver, like old, w chip adapt
# gpio-scx/patch.add-DEBUG    # enable all dev_dbg()s

# Cleanups

# finish printk -> dev_dbg() etc
gpio-scx/patch.pdev-pc8736x    # new drvr needs pdev too,
gpio-scx/patch.devdbg-nscgpio    # add device to 'vtable', use in dev_dbg()

# gpio-scx/patch.pin-config-view    # another 'c' 'command'
# gpio-scx/quiet-getset        # take out excess dbg stuff (pretty quiet
now)
gpio-scx/patch.shadow-current    # imitate scx200_gpio's shadow regs in
pc87*

# post KMentors-post patches ..

gpio-scx/patch.mutexes        # use mutexes for config-locks
gpio-scx/patch.viewpins-values    # extend dump to obsolete separate 'c' cmd

gpio-scx/patch.kconfig        # add stuff for kbuild

# TBC
# combine api26 with pdev, which is just one step.
# merge c&v commands to single do-all-fn
# delay viewpins, dump-diet should also un-ifdef it too.

This patch:

Removed editor format-control comments, and used scripts/Lindent to clean up
whitespace, then deleted the bogus chunks :-(
