| |
Use cpu_to_le32 to convert the constants to __le32 type before comparing them with p->des0 and p->des1 (they are __le32 type) and to fix following sparse warnings:
drivers/net/ethernet/stmicro/stmmac/dwxgmac2_descs.c:110:23: sparse: warning: restricted __le32 degrades to integer drivers/net/ethernet/stmicro/stmmac/dwxgmac2_descs.c:110:50: sparse: warning: restricted __le32 degrades to integer
