Subject: [PATCH 05/10] biosdecode: Clean up the PIR table output
|
|
|
60918b |
|
|
|
60918b |
* Remove entry numbers.
|
|
|
60918b |
* Use "Device" instead of "ID".
|
|
|
60918b |
* Put repeated code in a function.
|
|
|
60918b |
* Don't display unconnected links.
|
|
|
60918b |
* Shorten "slot number" to just "slot".
|
