linux-next: build failure after merge of the usb tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi all,

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

drivers/xen/unpopulated-alloc.c:17:21: error: 'list_count' redeclared as different kind of symbol
   17 | static unsigned int list_count;
      |                     ^~~~~~~~~~
In file included from include/linux/preempt.h:11,
                 from include/linux/spinlock.h:56,
                 from include/linux/mmzone.h:8,
                 from include/linux/gfp.h:7,
                 from drivers/xen/unpopulated-alloc.c:3:
include/linux/list.h:662:22: note: previous definition of 'list_count' with type 'size_t(struct list_head *)' {aka 'long unsigned int(struct list_head *)'}
  662 | static inline size_t list_count(struct list_head *head)
      |                      ^~~~~~~~~~

Caused by commit

  a9efc04cfd05 ("i915: Move list_count() to list.h for broader use")

I have used the usb tree from next-20221129 for today.
