Subject: [PATCH] power-supply: Constify static psy_tzd_ops struct
Date: Wed, 20 Jan 2021 17:54:26 +0800 [thread overview]
Message-ID: <20210120095427.10592-1-dj0227@163.com> (raw)
From: dongjian <dongjian@yulong.com>
The usage of this struct is to assign operation function's address
to the field in thermal_zone_device_ops, it is a const pointer.
make it const to allow the compiler to put it in read-only memory.
