Subject: dpaa2-eth: Fix passing zero to 'PTR_ERR' warning
From: YueHaibing <yuehaibing@xxxxxxxxxx>
[ Upstream commit 02afa9c66bb954c6959877c70d9e128dcf0adce7 ]
Fix smatch warning:
drivers/net/ethernet/freescale/dpaa2/dpaa2-eth.c:2419
alloc_channel() warn: passing zero to 'ERR_PTR'
setup_dpcon() should return ERR_PTR(err) instead of zero in error
handling case.
Fixes: d7f5a9d89a55 ("dpaa2-eth: defer probe on object allocate")
