Subject: [PATCH v3 7/9] platform/wmi: Make wmi_bus_class const
Date: Sat, 14 Mar 2026 18:52:47 +0100 [thread overview]
Message-ID: <20260314175249.16040-8-W_Armin@gmx.de> (raw)
In-Reply-To: <20260314175249.16040-1-W_Armin@gmx.de>
The functions class_register()/_unregister() and device_create()
both support taking a const pointer to the class struct. Use this
to mark wmi_bus_class as const so that it can be placed into
read-only memory for better security.
