kunit: provide kunit_platform_device_unregister()

2026-05-26T09:19:54+00:00

Tests may want to unregister a platform device as part of the test case logic. Using the regular platform_device_register() with kunit assertions may result in a platform device leak or otherwise requires cumbersome error handling. Provide a function that unregisters a kunit-managed platform device and drops the release action from the test's list.

platform: Add test managed platform_device/driver APIs

2024-07-29T22:33:12+00:00

Introduce KUnit resource wrappers around platform_driver_register(), platform_device_alloc(), and platform_device_add() so that test authors can register platform drivers/devices from their tests and have the drivers/devices automatically be unregistered when the test is done. This makes test setup code simpler when a platform driver or platform device is needed. Add a few test cases at the same time to make sure the APIs work as intended.
