Martin Fuzzey 65b60897a7 w1: fix data abort if no one wire bus master present ... When the "w1 bus" command is used with no bus master present a data abort may occur. This is because uclass_first_device() returns zero, but sets the output struct udevice pointer to NULL in the no device found case. Fix w1_get_bus() to account for this and return an error code as is expected by the callers.
