| Subject: USB: omninet: fix write_room |
| |
| 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. |
