Subject: [PATCH v8 04/12] thermal: qoriq: Embed per-sensor data into struct qoriq_tmu_data
Date: Tue, 10 Dec 2019 08:41:45 -0800 [thread overview]
Message-ID: <20191210164153.10463-5-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20191210164153.10463-1-andrew.smirnov@gmail.com>
Embed per-sensor data into struct qoriq_tmu_data so we can drop the
code allocating it. This also allows us to get rid of per-sensor back
reference to struct qoriq_tmu_data since now its address can be
calculated using container_of().
