6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Marek Vasut <marex@xxxxxxx> [ Upstream commit f96f700449b6d190e06272f1cf732ae8e45b73df ] Both ks8851_rx_skb_par() and ks8851_rx_skb_spi() call netif_rx(skb), inline the netif_rx(skb) call directly into ks8851_common.c and drop the .rx_skb callback and ks8851_rx_skb() wrapper. This removes one indirect call from the driver, no functional change otherwise.
