From: Al Cooper Date: Wed, 20 Aug 2014 13:41:57 +0000 (+0300) Subject: usb: xhci_suspend is not stopping the root hub timer for the shared HCD X-Git-Tag: v3.18-rc1~131^2~59 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=14e61a1bd986ac35be92c2dfb631a03a7c03abf4;p=platform%2Fkernel%2Flinux-exynos.git usb: xhci_suspend is not stopping the root hub timer for the shared HCD V2 - Restart polling (which will restart the timer) for the shared HCD in xhci_resume(). xhci_suspend() will stop the primary HCD's root hub timer, but leaves the shared HCD's timer running. This change adds stopping of the shared HCD timer.
