Title
usb: usbtmc: Fix bug in pipe direction for control transfers
Summary
In the Linux kernel, the following vulnerability has been resolved: usb: usbtmc: Fix bug in pipe direction for control transfers The syzbot fuzzer reported a minor bug in the usbtmc driver: usb 5-1: BOGUS control dir, pipe 80001e80 doesn't match bRequestType 0 WARNING: CPU: 0 PID: 3813 at drivers/usb/core/urb.c:412 usb_submit_urb+0x13a5/0x1970 drivers/usb/core/urb.c:410 Modules linked in: CPU: 0 PID: 3813 Comm: syz-executor122 Not tainted 5.17.0-rc5-syzkaller-00306-g2293be58d6a1 #0 ...

It's easy to fix.
