Subjectlinux-next: build failure after merge of the vhost tree
Hi all,

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

drivers/net/ethernet/atheros/atlx/atl1.c:2889:21: error: initialization of 'void (*)(struct net_device *, unsigned int)' from incompatible pointer type 'void (*)(struct net_device *)' [-Werror=incompatible-pointer-types]
2889 | .ndo_tx_timeout = atlx_tx_timeout,
| ^~~~~~~~~~~~~~~
drivers/net/ethernet/atheros/atlx/atl1.c:2889:21: note: (near initialization for 'atl1_netdev_ops.ndo_tx_timeout')

Caused by commit

29fd1db09264 ("netdev: pass the stuck queue to the timeout handler")

I applied the following patch:

Then I got another build failure:
