Haoxiang Li 47687092f2 w1: fix redundant counter decrement in w1_attach_slave_device() 
commit cc8f92e41e upstream.

In w1_attach_slave_device(), if __w1_attach_slave_device() fails,
put_device() -> w1_slave_release() is called to do the cleanup job.
In w1_slave_release(), sl->family->refcnt and sl->master->slave_count
have already been decremented. There is no need to decrement twice
in w1_attach_slave_device().

Fixes: 2c927c0c73 ("w1: Fix slave count on 1-Wire bus (resend)")

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 reStructuredText 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.
