Subject: powerpc/suspend: Add prototype for do_after_copyback()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=360f051d82ee0cc580edfffe9e8c0b93011ab86d;p=linux.git

powerpc/suspend: Add prototype for do_after_copyback()

With HIBERNATION=y the build breaks with:

  arch/powerpc/kernel/swsusp_64.c:14:6: error: no previous prototype for ‘do_after_copyback’ [-Werror=missing-prototypes]
  14 | void do_after_copyback(void)
     |      ^~~~~~~~~~~~~~~~~

do_after_copyback() is only called from asm, so there is no prototype,
nor any header where it makes sense to place one. Just add a prototype
in the C file to fix the build error.
