When binding to an ipv6 address, it calls ipv6_chk_addr() to check if this address is on any dev. If a socket binds to a l3mdev but no dev is passed to do this check, all l3mdev and slaves will be skipped and the check will fail. This patch is to pass the bound_dev to make sure the devices under the same l3mdev can be returned in ipv6_chk_addr(). When the bound_dev is not a l3mdev or l3slave, l3mdev_master_dev_rcu() will return NULL in __ipv6_chk_addr_and_flags(), it will keep compitable with before when NULL dev was passed.

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.
