Subject: [PATCH 03/13] module: unexport find_module and module_mutex
Date: Tue,  2 Feb 2021 13:13:24 +0100	[thread overview]
Message-ID: <20210202121334.1361503-4-hch@lst.de> (raw)
In-Reply-To: <20210202121334.1361503-1-hch@lst.de>

find_module is not used by modular code any more, and random driver code
has no business calling it to start with.
