Description
In the Linux kernel, the following vulnerability has been resolved:

media: mceusb: Use new usb_control_msg_*() routines

Automatic kernel fuzzing led to a WARN about invalid pipe direction in
the mceusb driver:

The reason for the warning is clear enough; the driver sends an
unusual read request on endpoint 0 but does not set the USB_DIR_IN bit
in the bRequestType field.

More importantly, the whole situation can be avoided and the driver
simplified by converting it over to the relatively new
usb_control_msg_recv() and usb_control_msg_send() routines. That's
what this fix does.
