usb: core: lpm: set lpm_capable for root hub device

2015-07-22T21:46:50Z

Commit 25cd2882e2fc ("usb/xhci: Change how we indicate a host supports Link PM.") removed the code to set lpm_capable for USB 3.0 super-speed root hub. The intention of that change was to avoid touching usb core internal field, a.k.a. lpm_capable, and let usb core to set it by checking U1 and U2 exit latency values in the descriptor. Usb core checks and sets lpm_capable in hub_port_init(). Unfortunately, root hub is a special usb device as it has no parent. Hub_port_init() will never be called for a root hub device. That means lpm_capable will by no means be set for the root hub. As the result, lpm isn't functional at all in Linux kernel. This patch add the code to check and set lpm_capable when registering a root hub device. It could be back-ported to kernels as old as v3.15, that contains the Commit 25cd2882e2fc ("usb/xhci: Change how we indicate a host supports Link PM.").

USB: fix use-after-free bug in usb_hcd_unlink_urb()

2015-01-31T17:05:06Z

The usb_hcd_unlink_urb() routine in hcd.c contains two possible use-after-free errors. The dev_dbg() statement at the end of the routine dereferences urb and urb->dev even though both structures may have been deallocated. This patch fixes the problem by storing urb->dev in a local variable (avoiding the dereference of urb) and moving the dev_dbg() up before the usb_put_dev() call.
