[ 10/12] SCSI: nsp32: use mdelay instead of large udelay constants

From: Greg Kroah-Hartman
Date: Tue Aug 13 2013 - 02:34:39 EST


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

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

From: Arnd Bergmann <arnd@xxxxxxxx>

commit b497ceb964a80ebada3b9b3cea4261409039e25a upstream.

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