commit 7e8b3dfef1 upstream.
The HOSTPC extension registers found in some EHCI implementations form
a variable-length array, with one element for each port. Therefore
the hostpc field in struct ehci_regs should be declared as a
zero-length array, not a single-element array.
This fixes a problem reported by UBSAN.
