Subject: [PATCH 00/12] clk: Unit test clk unregistration paths
Date: Wed, 14 Aug 2024 17:55:06 -0700 [thread overview]
Message-ID: <20240815005520.1192374-1-sboyd@kernel.org> (raw)
The clk_hw_unregister() path is rarely used and almost entirely
untested. Case in point, the first patch in this series that fixes a bug
due to unregistering a clk_hw and calling clk_put(). Add unit tests for
this code and test the consumer APIs to make sure the behavior stays
consistent.
The last patch is a WIP because I haven't gotten around to fixing all
the problems.
