Before changes:
The patch makes the parent of the device pointing to the pci_dev
structure. The parents portX devices are in /sys/devices which
should be removed based on your suggestions. Below is /sys/devices
before any changes made.
/sys/devices
|
__ ide0
|
__ pci0000:00
|
__ pnp0
|
__ port1
| |
| __ port1.00
| |
| __ port1.01
| .
| .
| .
|
__ port2
|
__ port3
|
__ system
After changes:
The parents portX devices are no longer necessary because port1.00
and port1.01 devices shoud have the parent of the pci_dev structure
(based on your suggestion). The patch does the following changes:
- remove code creating and handling the parent portX devices.
- rename portX.YZ to pcieYZ (for example port1.00 renamed to pcie00)
since portX is no longer needed.
- make pcieYZ have the parent of the pci_dev structure.
Below is /sys/devices after changes made to the patch.

Please let me know what you think of the changes.
