Subject: [POWERPC] wrapper: Rename offset in offset_devp()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=754e5f3f3a96264b96d5593242d81c7468af70cb;p=linux-beck.git

[POWERPC] wrapper: Rename offset in offset_devp()

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.
