Input: ims-pcu - validate control endpoint type
The driver currently assumes that the first endpoint of the control
interface is an interrupt IN endpoint without verifying it. A malicious
device could provide a different endpoint type, which would then be
passed to usb_fill_int_urb(), potentially leading to kernel warnings
or undefined behavior.
Verify that the control endpoint is an interrupt IN endpoint.
