Subject: [26/40] USB: omninet: fix write_room
Date: Tue, 10 Jan 2012 13:45:39 -0800 [thread overview]
Message-ID: <20120110214620.472107630@clark.kroah.org> (raw)
In-Reply-To: <20120110214630.GA14384@kroah.com>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <jhovold@gmail.com>
commit 694c6301e515bad574af74b6552134c4d9dcb334 upstream.
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.
