Subject: [PATCH net-next v3 1/4] netconsole: move init/cleanup functions lower
Date:   Tue, 10 Oct 2023 02:37:48 -0700
Message-Id: <20231010093751.3878229-2-leitao@debian.org>

Move alloc_param_target() and its counterpart (free_param_target())
to the bottom of the file. These functions are called mostly at
initialization/cleanup of the module, and they should be just above the
callers, at the bottom of the file.

From a practical perspective, having alloc_param_target() at the bottom
of the file will avoid forward declaration later (in the following
patch).

Nothing changed other than the functions location.
