Johan Hovold ed5e2515a3 USB: serial: keyspan_pda: fix write unthrottling 
commit 320f9028c7873c3c7710e8e93e5c979f4c857490 upstream.

The driver did not update its view of the available device buffer space
until write() was called in task context. This meant that write_room()
would return 0 even after the device had sent a write-unthrottle
notification, something which could lead to blocked writers not being
woken up (e.g. when using OPOST).

Note that we must also request an unthrottle notification is case a
write() request fills the device buffer exactly.

Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")
