Subject: [patch 158/176] net/fec: fix MMFR_OP type in fec_enet_mdio_write

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

------------------

From: Shawn Guo <shawn.guo@...escale.com>

commit 862f0982eadcea0e114576c57ea426d3d51a69a6 upstream.

FEC_MMFR_OP_WRITE should be used than FEC_MMFR_OP_READ in
a mdio write operation.

It's probably a typo introduced by commit:

e6b043d512fa8d9a3801bf5d72bfa3b8fc3b3cc8
netdev/fec.c: add phylib supporting to enable carrier detection (v2)
