At present the error code is never returned. Fix it. With this change, the following error is produced: test/dm/clk.c:50, dm_test_clk(): 0 == uclass_get_device_by_name(UCLASS_CLK, "clk-sbox", &dev_clk): Expected 0x0 (0), got 0xfffffffe (-2) Test: dm_test_clk: clk.c (flat tree) test/dm/clk.c:50, dm_test_clk(): 0 == uclass_get_device_by_name(UCLASS_CLK, "clk-sbox", &dev_clk): Expected 0x0 (0), got 0xfffffffe (-2) Also this causes a crash in sandbox: Test: dm_test_clk: clk.c Program received signal SIGSEGV, Segmentation fault. sandbox_clk_query_enable (dev=<optimized out>, id=id@entry=0) at drivers/clk/clk_sandbox.c:164 164 return priv->enabled[id]; (gdb) q A few other tests fail also, as marked.
