[PATCH 05/13] net: ravb: Stop DMA in case of failures on ravb_open()

From: Claudiu
Date: Mon Nov 20 2023 - 03:46:42 EST


From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>

In case ravb_phy_start() returns with error the settings applied in
ravb_dma_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")
