You need to "unroll" copy_to_user_ret(). There is no corresponding macro. Just test the condition and return -EFAULT (?; not looking at the source code) if it's invalid.
Don't know about "outs".
__bad_udelay means that some module used a too-large-parameter-value to udelay(). Linker should be telling you which module.
