Commit 44a3928324e9 ("drm/tests: Add Kunit Helpers") introduced the
|
|
drm_kunit_device_init() function but didn't document it properly. Add
|
|
that documentation.

|
|
+ * drm_kunit_device_init - Allocates a mock DRM device for KUnit tests
|
|
+ * @test: The test context object
|
|
+ * @features: Mocked DRM device driver features
|
|
+ * @name: Name of the struct &device to allocate
|
|
+ *
|
|
+ * This function allocates a new struct &device, creates a struct
|
|
+ * &drm_driver and will create a struct &drm_device using both.
|
|
+ *
|
|
+ * The device and driver are tied to the @test context and will get
|
|
+ * cleaned at the end of the test. The drm_device is allocated through
|
|
+ * devm_drm_dev_alloc() and will thus be freed through a device-managed
|
|
+ * resource.
|
|
+ *
|
|
+ * Returns:
|
|
+ * A pointer to the new drm_device, or an ERR_PTR() otherwise.
