Subject: [PATCH net-next 2/2] errqueue: include linux/time.h

From: Willem de Bruijn <willemb@...gle.com>

struct scm_timestamping has fields of type struct timespec. Now that
it is safe to include linux/time.h and time.h at the same time,
include linux/time.h directly in linux/errqueue.h

Without this patch, when compiling the following program after
make headers_install:

gcc -Wall -Werror -Iusr/include -c -xc - <<EOF
  #include <linux/errqueue.h>
  static struct scm_timestamping tss;
  int main(void) { tss.ts[0].tv_sec = 1; return 0; }
EOF

gcc gives this error:

  In file included from <stdin>:1:0:
  usr/include/linux/errqueue.h:33:18: error: array type has incomplete element type
    struct timespec ts[3];
