Subject: [PATCH 1/4] power: supply: core: Constify usb_types
Date: Mon, 13 Apr 2020 20:38:50 +0200 [thread overview]
Message-ID: <20200413183853.1088823-2-sebastian.reichel@collabora.com> (raw)
In-Reply-To: <20200413183853.1088823-1-sebastian.reichel@collabora.com>
usb_types is a list of USB types supported by the
hardware, which does not change at runtime. Let's
mark it as const for improved security.
