Subject: [PATCH v1 08/10] thermal: tsens: Get rid of 'id' field
Date: Thu,  9 Aug 2018 18:02:40 +0530
Message-ID: <3810cbe6b499d265d7e3fb97c408cb80a12d5850.1533815718.git.amit.kucheria@linaro.org> (raw)
In-Reply-To: <cover.1533815718.git.amit.kucheria@linaro.org>

The hw_id field in 'struct tsens_sensor' can do the job of tracking
unique ids for each sensor connected to each tsens device instance. It
also allows hw_ids to be overridden (e.g. 8916) in cases where some
sensors in a sequence are disabled on a particular platform.

Use the hw_id field instead of the id field consistently across the
tsens code.

While, we're at it, document the fields of struct tsens_sensor.
