From: Johan Hovold Date: Sun, 30 Sep 2018 16:03:11 +0000 (+0200) Subject: USB: serial: cypress_m8: fix interrupt-out transfer length X-Git-Tag: v5.4-rc1~2361^2~7^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=56445eef55cb5904096fed7a73cf87b755dfffc7;p=platform%2Fkernel%2Flinux-rpi.git USB: serial: cypress_m8: fix interrupt-out transfer length 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.
