br_switchdev_mdb_notify() is conditionally compiled only when
CONFIG_NET_SWITCHDEV=y and CONFIG_BRIDGE_IGMP_SNOOPING=y. It is called
from br_mdb.c, which is conditionally compiled only when
CONFIG_BRIDGE_IGMP_SNOOPING=y.
The shim definition of br_switchdev_mdb_notify() is therefore needed for
the case where CONFIG_NET_SWITCHDEV=n, however we mistakenly put it
there for the case where CONFIG_BRIDGE_IGMP_SNOOPING=n. This results in
build failures when CONFIG_BRIDGE_IGMP_SNOOPING=y and
CONFIG_NET_SWITCHDEV=n.
To fix this, put the shim definition right next to
br_switchdev_fdb_notify(), which is properly guarded by NET_SWITCHDEV=n.
Since this is called only from br_mdb.c, we need not take any extra
safety precautions, when NET_SWITCHDEV=n and BRIDGE_IGMP_SNOOPING=n,
this shim definition will be absent but nobody will be needing it.

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.
