skb_queue_len not being checked? Look at these two places: either
your analysis has a bug, or there's some wierd code...
skb_push and skb_pull return the new skb data region, but have more
important side effects. All these three can never error.

pcmcia code, or netfilter code? netfilter code always checks...

This is OK. Most people don't care if mod_timer had to delete the old
timer or not.
> del_timer : 36 : 444:
Whether ignoring this is OK or not is tricky. If del_timer returns
false, you either never added the timer, it has already finished, or
it is running *now* (SMP). Hence touching the timer struct contents
after an unchecked del_timer is v. v. suspect, eg:
del_timer(&mytimer);
kfree(mytimer->data);
Or an unchecked del_timer in module unload. del_timer_sync on the
other hand, is safe.
Keep up the great work!
