Message-Id: <b2f0db747a0e1bf3b57221b7fcde6623ad3011d1.1468571634.git.baolin.wang@linaro.org> Date: Fri, 15 Jul 2016 17:13:25 +0800 From: Baolin Wang <baolin.wang@...aro.org> To: balbi@...nel.org, gregkh@...uxfoundation.org Cc: mathias.nyman@...el.com, linux-usb@...r.kernel.org, linux-kernel@...r.kernel.org, broonie@...nel.org, baolin.wang@...aro.org Subject: [PATCH 1/4] usb: host: xhci: Move the xhci quirks checking to the right place It will reset the xhci quirks in xhci_gen_setup() function when xhci try to add one hcd, thus we need to move the XHCI_LPM_SUPPORT quirk checking after adding hcd.
