Subject[PATCH 5.4 076/102] net: axienet: Fix error return code in axienet_probe()
Date
From: Wei Yongjun <weiyongjun1@huawei.com>

[ Upstream commit eb34e98baf4ce269423948dacefea6747e963b48 ]

In the DMA memory resource get failed case, the error is not
set and 0 will be returned. Fix it by removing redundant check
since devm_ioremap_resource() will handle it.

Fixes: 28ef9ebdb64c ("net: axienet: make use of axistream-connected attribute optional")
