drivers/base/node: fold register_node() into register_one_node()

Browse Source 
Patch series "drivers/base/node: fold node register and unregister
functions", v2.

The first patch merges register_one_node() and register_node(), leaving a
single register_node() function.

The second patch merges unregister_one_node() and unregister_node(),
leaving a single unregister_node() function.

There are no functional changes in these patches.


This patch (of 2):

register_node() is only called from register_one_node().  This patch folds
register_node() into its only caller and renames register_one_node() to
register_node().

This reduces unnecessary indirection and simplifies the code structure. 
No functional changes are introduced.
