USB: Avoid runtime suspend loops for HCDs that can't handle suspend/resume

2014-06-11T19:03:26Z

commit 8ef42ddd9a53b73e6fc3934278710c27f80f324f upstream. Not all host controller drivers have bus-suspend and bus-resume methods. When one doesn't, it will cause problems if runtime PM is enabled in the kernel. The PM core will attempt to suspend the controller's root hub, the suspend will fail because there is no bus-suspend routine, and a -EBUSY error code will be returned to the PM core. This will cause the suspend attempt to be repeated shortly thereafter, in a never-ending loop. Part of the problem is that the original error code -ENOENT gets changed to -EBUSY in usb_runtime_suspend(), on the grounds that the PM core will interpret -ENOENT as meaning that the root hub has gotten into a runtime-PM error state. While this change is appropriate for real USB devices, it's not such a good idea for a root hub. In fact, considering the root hub to be in a runtime-PM error state would not be far from the truth. Therefore this patch updates usb_runtime_suspend() so that it adjusts error codes only for non-root-hub devices. Furthermore, the patch attempts to prevent the problem from occurring in the first place by not enabling runtime PM by default for root hubs whose host controller driver doesn't have bus_suspend and bus_resume methods.

USB: io_ti: fix firmware download on big-endian machines (part 2)

2014-06-11T19:03:26Z

commit c03890ff5e24a4bf59059f2d179f427559b7330a upstream. A recent patch that purported to fix firmware download on big-endian machines failed to add the corresponding sparse annotation to the i2c-header. This was reported by the kbuild test robot. Adding the appropriate annotation revealed another endianess bug related to the i2c-header Size-field in a code path that is exercised when the firmware is actually being downloaded (and not just verified and left untouched unless older than the firmware at hand). This patch adds the required sparse annotation to the i2c-header and makes sure that the Size-field is sent in little-endian byte order during firmware download also on big-endian machines. Note that this patch is only compile-tested, but that there is no functional change for little-endian systems.

xhci: delete endpoints from bandwidth list before freeing whole device

2014-06-11T19:03:24Z

commit 5dc2808c4729bf080487e61b80ee04e0fdb12a37 upstream. Lists of endpoints are stored for bandwidth calculation for roothub ports. Make sure we remove all endpoints from the list before the whole device, containing its endpoints list_head stuctures, is freed. This used to be done in the wrong order in xhci_mem_cleanup(), and triggered an oops in resume from S4 (hibernate).

USB: OHCI: fix problem with global suspend on ATI controllers

2014-06-07T20:25:32Z

commit c1db30a2a79eb59997b13b8cabf2a50bea9f04e1 upstream. Some OHCI controllers from ATI/AMD seem to have difficulty with "global" USB suspend, that is, suspending an entire USB bus without setting the suspend feature for each port connected to a device. When we try to resume the child devices, the controller gives timeout errors on the unsuspended ports, requiring resets, and can even cause ohci-hcd to hang; see http://marc.info/?l=linux-usb&m=139514332820398&w=2 and the following messages. This patch fixes the problem by adding a new quirk flag to ohci-hcd. The flag causes the ohci_rh_suspend() routine to suspend each unsuspended, enabled port before suspending the root hub. This effectively converts the "global" suspend to an ordinary root-hub suspend. There is no need to unsuspend these ports when the root hub is resumed, because the child devices will be resumed anyway in the course of a normal system resume ("global" suspend is never used for runtime PM). This patch should be applied to all stable kernels which include commit 0aa2832dd0d9 (USB: use "global suspend" for system sleep on USB-2 buses) or a backported version thereof.
