Subject: [PATCH] dm: test: Add tests for get/find uclass's device by name
This commit introduces simple tests for functions:
- uclass_find_device_by_name()
- uclass_get_device_by_name()
Tests added by this commit:
- Test: dm_test_uclass_devices_find_by_name: for uclass id: UCLASS_TEST_FDT
* get uclass's devices by uclass_find_first/next_device() each as 'testdev',
* for each returned device, call: uclass_find_device_by_name(),
with previously returned device's name as an argument ('testdev->name').
* for the found device ('founddev') check if:
* founddev != NULL
* testdev == founddev
* testdev->name == founddev->name (by strcmp)
- Test: dm_test_uclass_devices_get_by_name: for uclass id: UCLASS_TEST_FDT
* get uclass's devices by uclass_get_first/next_device() each as 'testdev',
* for each returned device, call: uclass_get_device_by_name(),
with previously returned device's name as an argument ('testdev->name').
* for the found device ('founddev') check if:
* founddev != NULL
* founddev is active
* testdev == founddev
* testdev->name == founddev->name (by strcmp)
