commit 8a8f3f4991761a70834fe6719d09e9fd338a766e upstream.
The driver allocates ring elements using GFP_DMA flags. There is no dependency from LAN743x hardware on memory allocation should be in DMA_ZONE. Hence modifying the flags to use only GFP_ATOMIC. This is consistent with other callers of lan743x_rx_init_ring_element().
