I disassemble the call function init_device_map,and the function 
check_device,I didn't find that you says.

init_device_map call check_deivce,then the control jump to the function 
check_device,then process continue.The process flow is correct  like the 
c source file's.

I guess you say is the binary code was optimized,isn't it? Counld you 
reference to me about the point?Thanks!
