Hi all,

After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/net/ethernet/mediatek/mtk_ppe_offload.c: In function 'mtk_flow_get_wdma_info':
drivers/net/ethernet/mediatek/mtk_ppe_offload.c:93:26: error: initialization of 'unsigned char' from 'const u8 *' {aka 'const unsigned char *'} makes integer from pointer without a cast [-Werror=int-conversion]
   93 |                 .daddr = addr,
      |                          ^~~~
drivers/net/ethernet/mediatek/mtk_ppe_offload.c:93:26: note: (near initialization for 'ctx.daddr[0]')
drivers/net/ethernet/mediatek/mtk_ppe_offload.c:91:42: error: missing braces around initializer [-Werror=missing-braces]
   91 |         struct net_device_path_ctx ctx = {
      |                                          ^
   92 |                 .dev = dev,
   93 |                 .daddr = addr,
      |                          {
   94 |         };
      |         }

Caused by commit

  cf2df74e202d ("net: fix dev_fill_forward_path with pppoe + bridge")

from Linus' tree interacting with commit

  a333215e10cb ("net: ethernet: mtk_eth_soc: implement flow offloading to WED devices")

from the net-next tree.

I have applied the following merge fix patch for today.
