WARNING:VSPRINTF_SPECIFIER_PX: Using vsprintf specifier '%px' potentially exposes the kernel memory 
layout, if you don't really need the address please consider using '%p'.
#38: FILE: drivers/net/ethernet/toshiba/ps3_gelic_net.c:171:
+		dev_err(dev, "%s:%d: head=%px\n", __func__, __LINE__,
+			card->rx_chain.head);


NOTE: For some of the reported defects, checkpatch may be able to
       mechanically convert to the typical style using --fix or --fix-inplace.

Commit 65f38d9720ac ("net/ps3_gelic: Cleanup debug code") has style problems, please review.
