Good old U-Boot style says we print a message when we start an
operation, and then an OK / failed when done.  When the system crashes
in this command, you can see at last where it crashed, i. e. what the
last running command was.

Your change breaks this - in the error path nothing gets printed.

This is even worse, as even though the system keeps running the user
has no indication of what failed...

I suggest to keep the printf() as before, and just fix the return code
thing.

Best regards,

Wolfgang Denk
