CVE-2025-38391

usb: typec: altmodes/displayport: do not index invalid pin_assignments

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

usb: typec: altmodes/displayport: do not index invalid pin_assignments

A poorly implemented DisplayPort Alt Mode port partner can indicate
that its pin assignment capabilities are greater than the maximum
value, DP_PIN_ASSIGN_F. In this case, calls to pin_assignment_show
will cause a BRK exception due to an out of bounds array access.

Prevent for loop in pin_assignment_show from accessing
invalid values in pin_assignments by adding DP_PIN_ASSIGN_MAX
value in typec_dp.h and using i < DP_PIN_ASSIGN_MAX as a loop
condition.
