Hi all,

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

/tmp/next/build/drivers/net/ethernet/renesas/rtsn.c:1381:27: error: initialization of 'void (*)(struct platform_device *)' from incompatible pointer type 'int (*)(struct platform_device *)' [-Werror=incompatible-pointer-types]
 1381 |         .remove         = rtsn_remove,
      |                           ^~~~~~~~~~~
/tmp/next/build/drivers/net/ethernet/renesas/rtsn.c:1381:27: note: (near initialization for 'rtsn_driver.<anonymous>.remove')

Caused by commit

  0edb555a65d1e ("platform: Make platform_driver::remove() return void")

interacting with

  b0d3969d2b4db ("net: ethernet: rtsn: Add support for Renesas Ethernet-TSN")

I have applied the below patch.
