The variable "tmout" is initialized in the prior  code "case 
USB_CHG_STATE_WAIT_FOR_DCD",
and this case will be executed before "if (tmout)", so I think it's a 
mis-warning for some
special compiler.

Could you provide me some suggestion about this warning? Should I upload 
a new patch to
fix this compiler mis-warning or just ignore it ï :-)
