Subject: backport commit ("c739b17a715c net: stmmac: don't attach interface until resume finishes") to linux-5.4-stable

Hi reviewers,

I suggest to backport 
commit "c739b17a715c net: stmmac: don't attach interface until resume finishes"
to linux-5.4 stable tree.

This patch fix resume issue by deferring netif_device_attach().

However, the patch cannot be cherry-pick directly on to stable-5.4.
A slightly change to the origin patch is required.
I'd like to provide the modification to stable-5.4 if it is needed.

commit: c739b17a715c6a850477189fb7c5f9a6af74f4bb
subject: net: stmmac: don't attach interface until resume finishes
kernel version to apply to: Linux-5.4

Thanks.
Macpaul Lin
