3.0-stable review patch. If anyone has any objections, please let us know.


From: Stanislaw Gruszka <sgruszka@xxxxxxxxxx>

commit b52398b6e4522176dd125722c72c301015d24520 upstream.

We should clear skb->data not skb itself. Bug was introduced by:
commit 0b8004aa12d13ec750d102ba4082a95f0107c649 "rt2x00: Properly
reserve room for descriptors in skbs".
