Let's cut-n-paste 2 more lines out of the file:
613 /* Allocate the rxmeta */
614 rxmeta = kzalloc(sizeof(struct p80211_rxmeta), GFP_ATOMIC);
615
616 if (rxmeta == NULL) {
617 netdev_err(wlandev->netdev,
618 "%s: Failed to allocate rxmeta.\n",
wlandev->name);
619 result = 1;
620 goto exit;
621 }
Lesson 1: Under what conditions will the kzalloc return NULL? If this happens,
what are the chances you'll have a chance to *see* the message? (Hint - what
size is that struct? If the kernel can't find that much free memory, what are
the chances you still have a functional syslog daemon?)
Lesson 2: The wisest thing ever said about checkpatch.pl:
" the code is more what you'd call "guidelines" than actual rules."
