4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xiaolei Wang <xiaolei.wang@xxxxxxxxxxxxx>
[ Upstream commit bf0497f53c8535f99b72041529d3f7708a6e2c0d ]
When fec_probe() fails or fec_drv_remove() needs to release the
fec queue and remove a NAPI context, therefore add a function
corresponding to fec_enet_init() and call fec_enet_deinit() which
does the opposite to release memory and remove a NAPI context.
Fixes: 59d0f7465644 ("net: fec: init multi queue date structure")
