Hi, all: when reviewing function usX2Y_rate_set, here may exist a NULL pointer deference if kmalloc_array failed or usb_alloc_urb failed, in cleanup, we should judge whether us->urb[i] is NULL first.

Right, that's a missing check. Would you submit the fix patch, or shall I write quickly?

thanks,

Takashi
