commit 8d2e77b39b8fecb794e19cd006a12f90b14dd077 upstream.
They are issues: - if 'input_allocate_device()' fails and return NULL, there is no need to free anything and 'input_free_device()' call is a no-op. It can be axed. - 'ret' is known to be 0 at this point, so we must set it to a meaningful value before returning
