Subject: [PATCH] platform/x86: wmi: declare device_type structure as constant
Date:   Sun, 28 Oct 2018 11:37:00 +0530
Message-Id: <20181028060700.22110-1-bhumirks@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The only usage of device_type structure is getting stored as
a reference in the type field of device structure. This type
field is declared const. Therefore, the device_type structure
can never be modified and can be declared as const.
