Phil Elwell c97d96b4e6 staging: bcm2835-audio: Fix memory corruption
The previous commit (0adbfd46) fixed a memory leak but also freed a
block in the success case, causing a stale pointer to be used with
potentially fatal results. Only free the vchi_instance block in the
case that vchi_connect fails; once connected, the instance is
retained for subsequent connections.

Simplifying the code by removing a bunch of gotos and returning errors
directly.

README

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.
