USB: usbtest: add a timeout for scatter-gather tests

2014-06-18T00:05:50Z

In usbtest, tests 5 - 8 use the scatter-gather library in usbcore without any sort of timeout. If there's a problem in the gadget or host controller being tested, the test can hang. This patch adds a 10-second timeout to the tests, so that they will fail gracefully with an ETIMEDOUT error instead of hanging.

usb: usbtest: add pattern check on pipe in phase of unlink read

2014-05-27T23:23:43Z

TEST 11 unlinks the URB read request for N times. When host and gadget both initialize pattern 1 (mod 63) data series to do IN transfer, the host side function should check the data buffer if it is as mod 63 series, because the data packet which host receivced will follow pattern 1. So this patch adds this checking action. Signed-off-by: Huang Rui Signed-off-by: Greg Kroah-Hartman

usb: usbtest: fix unlink write error with pattern 1

2014-05-27T23:23:43Z

TEST 12 and TEST 24 unlinks the URB write request for N times. When host and gadget both initialize pattern 1 (mod 63) data series to transfer, the gadget side will complain the wrong data which is not expected. Because in host side, usbtest doesn't fill the data buffer as mod 63 and this patch fixed it.

usb: usb5303: add support for reference clock specified in device tree

2014-05-27T23:19:04Z

USB3503 chip supports 8 values of reference clock. The value is specified by REF_SEL[1:0] pins and INT_N line. This patch add support for getting 'refclk' clock, enabling it and setting INT_N line according to the value of the gathered clock. If no clock has been specified, driver defaults to the old behaviour (assuming that clock has been specified by REF_SEL pins from primary reference clock frequencies table).

USB: yurex: fix race between probe() and read()

2014-05-27T23:03:58Z

There's a window during which read() would return 0 instead of a correct error for no data yet. Reorder initialization to fix the race. Signed-off-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman

USB: appledisplay: fix race between reading and writing from the device

2014-05-27T23:03:57Z

The workqueue handler may call appledisplay_bl_get_brightness() while user space calls appledisplay_bl_update_status(). As they share a buffer that must not happen. Use a mutex for mutual exclusion. Signed-off-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman
