Johan Hovold b0333e68dc 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.
