Subject: drivers/net/ethernet/nxp/lpc_eth.c: Call mdiobus_unregister before
mdiobus_free
From: Peter Senna Tschudin <[email protected]>
[ Upstream commit 57c10b61c84bfed68b1b317d6f507a392724b9c4 ]
Based on commit b27393aecf66199f5ddad37c302d3e0cfadbe6c0
Calling mdiobus_free without calling mdiobus_unregister causes
BUG_ON(). This patch fixes the issue.
The semantic patch that found this issue(http://coccinelle.lip6.fr/):
