Subject: [PATCH 55/79] serial: kill USF_CLOSING_* definitions

From: Alan Cox <alan@...ux.intel.com>

The serial layer for some reason uses different defines for the special
case close delays and then conditionally switches to/from the normal ones
in the ioctls.

Remove this rather pointless abstraction
