Hi all,

After merging the mm tree, today's linux-next build (i386 allmodconfig
clang14) produced this warning:

mm/shmem.c:1704:7: error: variable 'folio' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]

Introduced by commit

  2b58b3f33ba2 ("mm/shmem: convert shmem_swapin_page() to shmem_swapin_folio()")

'folio' is used in the error path.
