Subject: net: bcmgenet: fix bcmgenet_open()
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=fac25940c5e0d6f31d56bb2a704fadad6d5e382a;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

net: bcmgenet: fix bcmgenet_open()

If bcmgenet_init_dma() fails, it cleans up after itself. Rx and Tx
DMAs are off, and NAPI instances haven't been netif_napi_add()'ed.
Therefore, we need to skip calling bcmgenet_fini_dma() on the error
handling path. bcmgenet_resume() already does this correctly.
