[media] ttpci: Replace memset with eth_zero_addr
Use eth_zero_addr to assign the zero address to the given address array instead of memset when second argument is address of zero. Note that the 6 in the third argument of memset appears to represent an ethernet address size (ETH_ALEN). The Coccinelle semantic patch that makes this change is as follows: // <smpl> @eth_zero_addr@ expression e; @@ -memset(e,0x00,6); +eth_zero_addr(e); // </smpl> Signed-off-by: Vaishali Thakkar <vthakkar1994@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
