Subject[PATCH net-next] net: hix5hd2_gmac: Remove unneeded cast from memory allocation
Date

Coccinelle emits WARNING:

./drivers/net/ethernet/hisilicon/hix5hd2_gmac.c:1027:9-23: WARNING:
casting value returned by memory allocation function to (struct sg_desc *) is useless.

This issue was detected by using the Coccinelle software.
