3.16.36-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Neil Armstrong <narmstrong@xxxxxxxxxxxx>
commit 99164f9e62a391b5f4b7923b624d182b5d2859e0 upstream.
In order to avoid an Unbalanced pm_runtime_enable in the DaVinci
emac driver when the device is removed and re-probed, and a
pm_runtime_disable() call in davinci_emac_remove().
Actually, using unbind/bind on a TI DM8168 SoC gives :
$ echo 4a120000.ethernet > /sys/bus/platform/drivers/davinci_emac/unbind
net eth1: DaVinci EMAC: davinci_emac_remove()
$ echo 4a120000.ethernet > /sys/bus/platform/drivers/davinci_emac/bind
davinci_emac 4a120000.ethernet: Unbalanced pm_runtime_enable
Cc: Brian Hutchinson <b.hutchman@xxxxxxxxx>
