Subject: [PATCH v6 3/5] of/platform: Add stubs for of_platform_device_create/destroy()
Date: Mon,  5 Apr 2021 13:18:15 -0700
Message-ID: <20210405124900.v6.3.I08fd2e1c775af04f663730e9fb4d00e6bbb38541@changeid> (raw)
In-Reply-To: <20210405201817.3977893-1-mka@chromium.org>

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