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

From: Moritz Fischer <[email-masked]>
Date: Mon, 14 Sep 2020 21:24:51 -0700

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

Signed-off-by: Moritz Fischer <[email-masked]>

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
