the arc fimware can be configured with a password that is used to
restrict changes to its configuration. in our case we want to be
able to disable or enable the alarm. if a password is set though,
the firmware will reject that request with a PASSWORD_REQUIRED
response code. this change lets the kernel return EPERM instead of
EIO in that case.
if you dont have a password set on the firmware you can configure
the alarm just fine.
