Subject: [PATCH 1/2] wrapper: rename offset in offset_devp().

From: Scott Wood <[email-masked]>
Date: Tue, 11 Dec 2007 15:23:04 -0600

fdt_wrapper_create_node passes a variable called offset to offset_devp(),
which uses said parameter to initialize a local variable called offset.

Due to one of the odder aspects of the C language, the result is an
undefined variable, with no error or warning.
