Subject: [PATCH v2 5/6] net: ravb: Stop DMA in case of failures on ravb_open()

From: Claudiu Beznea <[email protected]>

In case ravb_phy_start() returns with error the settings applied in
ravb_dmac_init() are not reverted (e.g. config mode). For this call
ravb_stop_dma() on failure path of ravb_open().

Fixes: a0d2f20650e8 ("Renesas Ethernet AVB PTP clock driver")
