Revert "USB / PM: Allow USB devices to remain runtime-suspended when sleeping"

2016-05-02T15:44:31Z

This reverts commit e3345db85068ddb937fc0ba40dfc39c293dad977, which broke system resume for a large class of devices. Devices that after having been reset during resume need to be rebound due to a missing reset_resume callback, are now left in a suspended state. This specifically broke resume of common USB-serial devices, which are now unusable after system suspend (until disconnected and reconnected) when USB persist is enabled. During resume, usb_resume_interface will set the needs_binding flag for such interfaces, but unlike system resume, run-time resume does not honour it.

The usb_get_phy() function returns either a valid pointer to phy or ERR_PTR() error, check for NULL always fails and may lead to oops on error path, fix this issue. Signed-off-by: Vladimir Zapolskiy Signed-off-by: Bin Liu Signed-off-by: Greg Kroah-Hartman

Revert "usb: musb: musb_host: Enable HCD_BH flag to handle urb return in bottom half"

2016-04-26T21:50:02Z

This reverts commit 2035772010db634ec8566b658fb1cd87ec47ac77. Commit 20357720 claims throughput improvement for MSC/UVC, but I don't see much improvement. Following are the MSC measurement using dd on AM335x GP EVM. with BCD_BH: read: 14.9MB/s, write: 20.9MB/s without BCD_BH: read: 15.2MB/s, write: 21.2MB/s However with this commit the following regressions have been observed. 1. ASIX usb-ethernet dongle is completely broken on UDP RX. 2. Unpluging a 3G modem, which uses option driver, behind a hub causes console log flooding with the following message. option_instat_callback: error -71 Signed-off-by: Bin Liu Signed-off-by: Greg Kroah-Hartman

usb: musb: gadget: nuke endpoint before setting its descriptor to NULL

2016-04-26T21:50:02Z

Some functions, such as f_sourcesink, rely on an endpoint's desc field during their requests' complete() callback, so clear it only _after_ nuking all requests to avoid NULL pointer dereference. Signed-off-by: Tal Shorer Signed-off-by: Bin Liu Signed-off-by: Greg Kroah-Hartman

usb: gadget: f_fs: Fix use-after-free

2016-04-20T07:38:06Z

When using asynchronous read or write operations on the USB endpoints the issuer of the IO request is notified by calling the ki_complete() callback of the submitted kiocb when the URB has been completed. Calling this ki_complete() callback will free kiocb. Make sure that the structure is no longer accessed beyond that point, otherwise undefined behaviour might occur.

usb: dwc3: gadget: Fix suspend/resume during device mode

2016-04-18T09:35:18Z

Gadget controller might not be always active during system suspend/resume as gadget driver might not have yet been loaded or might have been unloaded prior to system suspend. Check if we're active and only then perform necessary actions during suspend/resume. Signed-off-by: Roger Quadros Signed-off-by: Felipe Balbi
