Subject: [PATCH v2 1/4] thermal: of: Extend of-thermal.c to provide number of trip points
Date: Thu, 20 Nov 2014 17:21:25 +0100 [thread overview]
Message-ID: <1416500488-7232-2-git-send-email-l.majewski@samsung.com> (raw)
In-Reply-To: <1416500488-7232-1-git-send-email-l.majewski@samsung.com>
This patch extends the of-thermal.c to provide information about number of
available trip points.
Signed-off-by: Lukasz Majewski <l.majewski@samsung.com>
---
Changes for v2:
- Provide detailed (doxygen like) description of the of_thermal_get_ntrips()
method
- Check for data pointer not being NULL
