dm: core: Mirror the chosen node parse logic in the livetree scanning
Commit f2006808f099: ("dm: core: parse chosen node") added a logic to parse the chosen node during dm_scan_fdt_node(), but unfortunately it missed adding the same logic in dm_scan_fdt_live(). This mirrors the logic in the livetree version. The weird thing is that commit f2006808f099 did update the test case to test such logic, but even if I reset to that commit, the test case still fails, and I have no idea how it could pass. With this fix, the following 2 test cases now pass: Test: dm_test_bus_children: bus.c test/dm/bus.c:112, dm_test_bus_children(): num_devices == list_count_items(&uc->dev_head): Expected 7, got 6 Test: dm_test_fdt: test-fdt.c test/dm/test-fdt.c:184, dm_test_fdt(): num_devices == list_count_items(&uc->dev_head): Expected 7, got 6 Fixes: f2006808f099 ("dm: core: parse chosen node") Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
