Two patches request for 3.18 stable

When going through the tree, I found some of the patches are backported incorrectly and they have been fixed on 4.4.

So I would like to request these 2 patches from 4.4 stable to get ported to 3.18:

Revert "led: core: Fix brightness setting when setting delay_off=0" (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/comm...)

xhci: Fix ring leak in failure path of xhci_alloc_virt_device() (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/comm...)

Thanks. Wang
