From 694c6301e515bad574af74b6552134c4d9dcb334 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Sun, 6 Nov 2011 19:06:21 +0100 Subject: [PATCH] USB: omninet: fix write_room Fix regression introduced by commit 507ca9bc047666 ([PATCH] USB: add ability for usb-serial drivers to determine if their write urb is currently being used.) which inverted the logic in write_room so that it returns zero when the write urb is actually free.
