Re: [PATCH] drivers: staging: ft1000: ft1000-usb: initialize 'status' with STATUS_SUCCESS in request_code_segment()

[Chen Gang <gang.chen.5i5j@gmail.com>]

Oh, another member has already fixed it (found earlier than me), and
integrated it into next-20131203 tree, so this patch is obsoleted.

The related git commit is "8aced95 staging: ft1000: fix use of
potentially uninitialized variable"

Thanks.
