This and the following patches don't build, please make sure
allmodconfig builds correctly. Here's an example failure, but
IDK if there isn't more:

drivers/net/ethernet/ti/davinci_emac.c: In function ‘emac_dev_open’:
drivers/net/ethernet/ti/davinci_emac.c:1469:3: error: too few arguments to function ‘emac_set_coalesce’
 1469 |   emac_set_coalesce(ndev, &coal);
