If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 0521cfd06e1ebcd575e7ae36aab068b38df23850 Mon Sep 17 00:00:00 2001 From: Peter Chen <peter.chen@xxxxxxxxxxxxx> Date: Mon, 17 Aug 2015 10:23:03 +0800 Subject: usb: host: ehci-sys: delete useless bus_to_hcd conversion From: Peter Chen <peter.chen@xxxxxxxxxxxxx> commit 0521cfd06e1ebcd575e7ae36aab068b38df23850 upstream. The ehci platform device's drvdata is the pointer of struct usb_hcd already, so we doesn't need to call bus_to_hcd conversion again.
