Subject: [PATCH v23 1/3] of/platform: Add stubs for of_platform_device_create/destroy()
Date: Wed, 22 Jun 2022 14:49:29 -0700	[thread overview]
Message-ID: <20220622144857.v23.1.I08fd2e1c775af04f663730e9fb4d00e6bbb38541@changeid> (raw)
In-Reply-To: <20220622214931.1914770-1-mka@chromium.org>

Code for platform_device_create() and of_platform_device_destroy() is
only generated if CONFIG_OF_ADDRESS=y. Add stubs to avoid unresolved
symbols when CONFIG_OF_ADDRESS is not set.
