Subject: [ 58/60] SCSI: nsp32: use mdelay instead of large udelay constants

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@...db.de>

commit b497ceb964a80ebada3b9b3cea4261409039e25a upstream.

ARM cannot handle udelay for more than 2 miliseconds, so we
should use mdelay instead for those.
