Subject: [SCSI] nsp32: use mdelay instead of large udelay constants
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=b497ceb964a80ebada3b9b3cea4261409039e25a;p=deliverable%2Flinux.git

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

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