Yue Haibing 219b1aed7b ipv6: mcast: Add ip6_mc_find_idev() helper
[ Upstream commit 60c481d4ca ]

Extract the same code logic from __ipv6_sock_mc_join() and
ip6_mc_find_dev(), also add new helper ip6_mc_find_idev() to
reduce redundancy and enhance readability.

No functional changes intended.

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.
