Device name are typically longer than 8 characters. This leads to ragged
output.
Only the I and O bit of the device flags are of interest for the user.
Writing a hexadecimal number is just confusing.
Before the patch the output looked like this:
=> coninfo
List of available devices:
pl011@9000000 00000007 IO stdin stdout stderr
serial 00000003 IO
usbkbd 00000001 I.
With the patch the output looks like this:
=> coninfo
List of available devices
|-- pl011@9000000 (IO)
| |-- stdin
| |-- stdout
| |-- stderr
|-- serial (IO)
|-- usbkbd (I)
