Hi, While working on 3.5 kernel, I came across commit c3897aa5386faba77e5bbdf94902a1658d3a5b11 xhci: Disable D3cold for buggy TI redrivers. which states: This patch should be backported to kernels as old as 3.2, that contain the commit 71c731a296f1b08a3724bd1b514b64f1bda87a23 "usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP Hardware" However, this commit actually makes usage of no_d3cold field in struct pci_dev, which doesn't exist in older kernels: + if (xhci_compliance_mode_recovery_timer_quirk_check()) + pdev->no_d3cold = true; Could someone advise on this? If this patch really is applicable to this kernel, can we get some help on the backport (at least for the 3.2, 3.4 and 3.5 kernels)?
