Subject: [PATCH 03/24 v2] USB: EHCI: remove Loongson 1B EHCI driver.
The platform code registering the Loongson 1B EHCI driver has now been
converted to register the ehci-platform driver instead, thus obsoleting the
ehci-ls1x driver, which can be removed.
Signed-off-by: Florian Fainelli <florian@...nwrt.org>
