[PATCH 0/2] prevent potential access of uninitialized members in can_rcv() and canfd_rcv()

[Anant Thazhemadam]

In both can_rcv(), and canfd_rcv(), when skb->len = 0, cfd->len 
(which is uninitialized) is accessed by pr_warn_once().

Performing the validation check for cfd->len separately, after the 
validation check for skb->len is done, resolves this issue in both 
instances, without compromising the degree of detail provided in the
log messages.
