This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.

v2:
 - Provided some descriptions to exported functions

Lee Jones (10):
  of: device: Fix function name in header and provide missing
    descriptions
  of: dynamic: Fix incorrect parameter name and provide missing
    descriptions
  of: platform: Demote kernel-doc abuse
  of: base: Fix some formatting issues and provide missing descriptions
  of: property: Provide missing member description and remove excess
    param
  of: address: Provide descriptions for 'of_address_to_resource's params
  of: fdt: Demote kernel-doc abuses and fix function naming

I still see some warnings (note this is with DT files added to doc
build). Can you send follow-up patches:

../include/linux/of.h:1193: warning: Function parameter or member
'output' not described in 'of_property_read_string_index'
../include/linux/of.h:1193: warning: Excess function parameter
'out_string' description in 'of_property_read_string_index'
../include/linux/of.h:1461: warning: cannot understand function
prototype: 'enum of_overlay_notify_action '
../drivers/of/base.c:1781: warning: Excess function parameter 'prob'
description in '__of_add_property'
../drivers/of/base.c:1804: warning: Excess function parameter 'prob'
description in 'of_add_property'
../drivers/of/base.c:1855: warning: Function parameter or member
'prop' not described in 'of_remove_property'
../drivers/of/base.c:1855: warning: Excess function parameter 'prob'
description in 'of_remove_property'

You don't want much do you! ;)

Sure, I plan to clean up all of the kernel with subsequent patches.

BTW, there some more which I guess W=1 doesn't find:

What command did you use to find these?
