Subject: linux-next: build failure after merge of the vfs tree

Hi all,

After merging the vfs tree, today's linux-next build (sparc defconfig)
failed like this:

arch/sparc/kernel/ptrace_32.c: In function 'setregs_set':
arch/sparc/kernel/ptrace_32.c:271:2: error: 'ret' undeclared (first use in this function); did you mean 'net'?
  ret = user_regset_copyin(&pos, &count, &kbuf, &ubuf,
  ^~~
  net


Caused by commit

  cf921bf15c62 ("sparc32: get rid of odd callers of copy_regset_from_user()")

I added this patch for today.
