    USB: serial: pl2303: fix NULL-deref at open · 76ab439e
    Johan Hovold authored
    Fix NULL-pointer dereference in open() should a type-0 or type-1 device
    lack the expected endpoints:
    
    Unable to handle kernel NULL pointer dereference at virtual address 00000030
    ...
    PC is at pl2303_open+0x38/0xec [pl2303]
    
    Note that a missing interrupt-in endpoint would have caused open() to
    fail.
