From: Johan Hovold Date: Sun, 6 Nov 2011 18:06:21 +0000 (+0100) Subject: USB: omninet: fix write_room X-Git-Tag: v3.2.1~11 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b4868343c4dde5315ffebc08de71ddffdd1460d8;p=karo-tx-linux.git USB: omninet: fix write_room 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.
