the following patch

diff --git a/drivers/net/wireless/ti/wl1251/rx.c 
b/drivers/net/wireless/ti/wl1251/rx.c
index 123c4bb..cde0eaf 100644

         wl1251_mem_read(wl, rx_packet_ring_addr, rx_buffer, length);

         /* The actual length doesn't include the target's alignment */
-       skb->len = desc->length  - PLCP_HEADER_LENGTH;
+       skb_trim(skb, desc->length - PLCP_HEADER_LENGTH);

         fc = (u16 *)skb->data;

seems to fix the issue, including those "corrupt probe response" 
messages in dmesg log (I took that 'skb_trim' from the original Nokia 
kernel). Will send a properly formatted patch shortly.

Thanks,
Ivo
