Is there a reason to use device ID over device label?

[mrjayviper]

So I'm trying to create a DSDT patch and along the way I'm learning things.

 

I've notice some examples I've seen uses device ID while other uses the device label.

 

Any pros/cons over the other? I can see myself leaning towards device label since it's easier to read/relate?

 

thanks a lot!

 

example: both lines refer to the PIC device except the 2nd one uses the device ID

into device label PIC code_regex IRQNoFlags\s\(\)\n\s+\{(\d+)\} remove_matched;

into device name_hid PNP0000 code_regex IRQNoFlags\s\(\)\n\s+\{(\d+)\} remove_matched;

Hi,

 

Both your examples are equal. "Search for xxx and xxx" 

 

The difference is, one searches for the name of a device, the other for the device id.

 

I would not search by device, but by code tbh.

looking at your answer, seems there's really no advantage over the other. more like personal choice? thanks again

Indeed, just what is easier for you. 

 

I must note, for example Lable PIC is DSDT(hardware) specific, where HID is not. Went a bit retard on my previous post.
