Subject: [PATCH v2 06/13] thermal: qoriq: Embed per-sensor data into struct qoriq_tmu_data
Date: Fri, 22 Feb 2019 12:05:01 -0800	[thread overview]
Message-ID: <20190222200508.26325-7-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190222200508.26325-1-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
caluclated using container_of().
