Could we follow the general kernel rule here and return 0 for success,
and < 0 on failure?
I made this to return 1, just because the next patch in the series would
make it
return session_restart. Depending on which the musb_platform_reset()
would return
whether actual reset of IP (reset_done) is done or not .
Thanks,
Daniel
