[PATCH] 2.4.7 tiny NTFS fix

[Anton Altaparmakov <aia21@cus.cam.ac.uk>]

Linus,

Please apply below patch (this time properly inlined I hope). It is
against 2.4.7-pre8 but should apply cleanly to 2.4.7. It adds a return
value check.

Thanks to Rasmus Andersen for initial patch.

Best regards,

	Anton
