linux-next: build warning after merge of the vhost tree

Hi all,

After merging the vhost tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

drivers/vhost/vhost.c: In function 'fetch_buf_packed':
drivers/vhost/vhost.c:2568:1: warning: no return statement in function returning non-void [-Wreturn-type]
 2568 | }
      | ^

Introduced by commit
