Subject: [PATCH 5.5 161/176] ubifs: Fix ino_t format warnings in orphan_delete()

From: Geert Uytterhoeven <geert@...ux-m68k.org>

commit 155fc6ba488a8bdfd1d3be3d7ba98c9cec2b2429 upstream.

On alpha and s390x:

    fs/ubifs/debug.h:158:11: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 4 has type ‘ino_t {aka unsigned int}’ [-Wformat=]
    ...
    fs/ubifs/orphan.c:132:3: note: in expansion of macro ‘dbg_gen’
       dbg_gen("deleted twice ino %lu", orph->inum);
    ...
    fs/ubifs/orphan.c:140:3: note: in expansion of macro ‘dbg_gen’
       dbg_gen("delete later ino %lu", orph->inum);

__kernel_ino_t is "unsigned long" on most architectures, but not on
alpha and s390x, where it is "unsigned int".  Hence when printing an
ino_t, it should always be cast to "unsigned long" first.

Fix this by re-adding the recently removed casts.
