Subject: [PATCH] kobject: Replace ALL occurrences of '/' with '!' instead of only the first one.

From: Ingo Oeser <ioe-lkml@...eria.de>

A recent patch from Kay Sievers <kay.sievers@...y.org>
replaced the first occurrence of '/' with '!' as needed for block devices.

Now do some cheap defensive coding and replace all of them to avoid future
issues in this area.

Signed-off-by: Ingo Oeser <ioe-lkml@...eria.de>

To answer your questions:
> Do you know of block devices with more than one?

No, just defensive coding :-)

> Nice, care to send a follow-on patch for this?

Linus just pulled, so I generated it against his latest tree.
