All driver model tests have a dm_test_ prefix. Ignore it when matching a test name. This makes it easier to run individual tests, like this: ./sandbox/u-boot -d ./sandbox/arch/sandbox/dts/test.dtb \ -c "ut dm clk_periph" We can use 'clk_periph' instead of 'dm_test_clk_periph'. Also print a message if the requested test is not found. Signed-off-by: Simon Glass <sjg@chromium.org>
