[patch 42/46] ACPI: EC: revert msleep patch

[Greg KH]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

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

From: Alexey Starikovskiy <astarikovskiy@xxxxxxx>

commit 1cfe62c8010ac56e1bd3827e30386a87cc2f3594 upstream.

With the better solution for EC interrupt storm issue,
there is no need to use msleep over udelay.
