Clang warns (trimmed the second warning for brevity):
../net/netfilter/nf_flow_table_offload.c:342:2: warning: variable
'offset' is used uninitialized whenever switch default is taken
[-Wsometimes-uninitialized]
default:
^~~~~~~
../net/netfilter/nf_flow_table_offload.c:346:57: note: uninitialized use
occurs here
flow_offload_mangle(entry, flow_offload_l4proto(flow), offset,
^~~~~~
../net/netfilter/nf_flow_table_offload.c:331:12: note: initialize the
variable 'offset' to silence this warning
u32 offset;
^
= 0
Match what was done in the flow_offload_ipv{4,6}_{d,s}nat functions and
just return in the default case, since port would also be uninitialized.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
