Subject: [PATCH net-next v2 2/3] net: dec: tulip: de2104x: Replace pci_enable_device with devres version

Replace pci_enable_device() with its devres counterpart
pcim_enable_device().

Signed-off-by: Moritz Fischer <mdf@...nel.org>
---

Note: Please check my logic on this, it would seem to me
calling pci_disable_device() on devices enabled with
pcim_enable_device() *should* be fine.

Changes from v1:
- Fixed missing replace for resume function
