[ Upstream commit 3427beb6375d04e9627c67343872e79341a684ea ]
With gcc 4.1:
net/rxrpc/output.c: In function ‘rxrpc_send_data_packet’:
net/rxrpc/output.c:338: warning: ‘ret’ may be used uninitialized in this function
Indeed, if the first jump to the send_fragmentable label is made, and
the address family is not handled in the switch() statement, ret will be
used uninitialized.
Fix this by BUG()'ing as is done in other places in rxrpc where internal
support for future address families will need adding. It should not be
possible to reach this normally as the address families are checked
up-front.
Fixes: 5a924b8951f835b5 ("rxrpc: Don't store the rxrpc header in the Tx queue sk_buffs")

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
