Hello all,

I am new to the realm of linux kernel development. I've been sending in small
patches to fix check-patch warnings. I was fixing up the file listed in the
subject when I came across this warning.

drivers/staging/wlan-ng/p80211conv.c:622: WARNING: Possible unnecessary 'out of
memory' message

Source Code:

if (rxmeta == NULL) {
                netdev_err(wlandev->netdev,
                           "%s: Failed to allocate rxmeta.\n", wlandev->name);
                result = 1;
                goto exit;
}

What is this warning about? How do I go about fixing it?

A "meta" comment, if you don't understand the warning, why would you
want to do anything about it?

thanks,
