Subject: [PATCH 2/4] thermal: zx2967: constify thermal_zone_of_device_ops structures
Date: Sat,  5 Aug 2017 22:37:15 +0200	[thread overview]
Message-ID: <1501965437-30730-3-git-send-email-Julia.Lawall@lip6.fr> (raw)
In-Reply-To: <1501965437-30730-1-git-send-email-Julia.Lawall@lip6.fr>

The thermal_zone_of_device_ops structure is only passed as the fourth
argument to thermal_zone_of_sensor_register, which is declared as const.
Thus the thermal_zone_of_device_ops structure itself can be const.

Done with the help of Coccinelle.
