USB: ftdi_sio: fix null deref at port probe
commit aea1ae8760314e072bf1b773521e9de5d5dda10d upstream.
Fix NULL-pointer dereference when probing an interface with no
endpoints.
These devices have two bulk endpoints per interface, but this avoids
crashing the kernel if a user forces a non-FTDI device to be probed.
Note that the iterator variable was made unsigned in order to avoid
a maybe-uninitialized compiler warning for ep_desc after the loop.
Fixes: 895f28badce9 ("USB: ftdi_sio: fix hi-speed device packet size
calculation")
