| Subject: USB: serial: cypress_m8: fix interrupt-out transfer length |
| |
| From: Johan Hovold <johan@kernel.org> |
| |
| [ Upstream commit 56445eef55cb5904096fed7a73cf87b755dfffc7 ] |
| |
| Fix interrupt-out transfer length which was being set to the |
| transfer-buffer length rather than the size of the outgoing packet. |
| |
| Note that no slab data was leaked as the whole transfer buffer is always |
| cleared before each transfer. |
| |
| Fixes: 9aa8dae7b1fa ("cypress_m8: use usb_fill_int_urb where appropriate") |
