usbfs allows user space to pass down an URB which sets URB_SHORT_NOT_OK for output URBs. That causes usbcore to log messages without limit for a nonsensical disallowed combination. The fix is to silently drop the attribute in usbfs. The problem is reported to exist since 3.14 https://www.virtualbox.org/ticket/13085Signed-off-by:

The 7023 product id is the generic product id for the Etron EJ168, it is not specific to the version found on the Asrock P67 motherboard. The same id is e.g. also used on Gigabyte motherboards and on no-name pci-e usb-3 addon cards. Signed-off-by:

Streams on the EJ168 do not work as they should. I've spend 2 days trying to get them to work, but without success. The first problem is that when ever you ring the stream-ring doorbell, the controller starts executing trbs at the beginning of the first ring segment, event if it ended somewhere else previously. This can be worked around by allowing enqueing only one td (not a problem with how streams are typically used) and then resetting our copies of the enqueueing en dequeueing pointers on a td completion to match what the controller seems to be doing. This way things seem to start working with uas and instead of being able to complete only the very first scsi command, the scsi core can probe the disk. But then things break later on when td-s get enqueued with more then one trb. The controller does seem to increase its dequeue pointer while executing a stream-ring (data transfer events I inserted for debugging do trigger). However execution seems to stop at the final normal trb of a multi trb td, even if there is a data transfer event inserted after the final trb. The first problem alone is a serious deviation from the spec, and esp. dealing with cancellation would have been very tricky if not outright impossible, but the second problem simply is a deal breaker altogether, so this patch simply disables streams. Note this will cause the usb-storage + uas driver pair to automatically switch to using usb-storage instead of uas on these devices, essentially reverting to the 3.14 and earlier behavior when uas was marked CONFIG_BROKEN. https://bugzilla.redhat.com/show_bug.cgi?id=1121288 https://bugzilla.kernel.org/show_bug.cgi?id=80101 Cc: stable@vger.kernel.org # 3.15 Signed-off-by:

Some jmicron uas chipsets act up (they disconnect from the bus) when sending more then 32 commands to them at once. Rather then building an ever growing list with usb-id based quirks for devices using this chipset, simply reduce the qdepth to 32 when connected over usb-2. 32 should be plenty to keep things close to maximum possible throughput on usb-2.

Correct typo in the name of the type given to sizeof. Because it is the size of a pointer that is wanted, the typo has no impact on compilation or execution.

This patch adds a usb quirk to support devices with interupt endpoints and bInterval values expressed as microframes. The quirk causes the parse endpoint function to modify the reported bInterval to a standards conforming value. There is currently code in the endpoint parser that checks for bIntervals that are outside of the valid range (1-16 for USB 2+ high speed and super speed interupt endpoints). In this case, the code assumes the bInterval is being reported in 1ms frames. As well, the correction is only applied if the original bInterval value is out of the 1-16 range. With this quirk applied to the device, the bInterval will be accurately adjusted from microframes to an exponent. Signed-off-by:

Merge tag 'for_3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/kishon/linux-phy into usb-next Kishon writes: for_3.17 Adds regulator support in PHY core. PHY core is modified to support representation of multi-phy PHY providers with each individual PHY as sub-node OF PHY provider node. New PHY drivers adapted to PHY framework (hix5hd2 SATA PHY, QCOM APQ8064 SATA PHY, QCOM IPQ806x SATA PHY, Berlin SATA PHY and MiPHY356x). Existing TI PIPE3 PHY can now be used for PCIe too. Includes misc fixes and cleanups.

-ENODEV is interpreted by the generic driver probing function as a non-matching driver. This leads to a missing probe failure message.

Section 4.4.7.2 "Interrupt Transfer Bandwidth Requirements" of the USB3.0 spec says: A zero-length data payload is a valid transfer and may be useful for some implementations. So, extend the logic of allowing URB_ZERO_PACKET to interrupt urbs too. Otherwise, the kernel throws warning of BOGUS transfer flags. Signed-off-by:

In case of multi-phy PHY providers, each PHY should be modeled as a sub node of the PHY provider.

The Berlin SoC has a two SATA ports. Add a PHY driver to handle them. The mode selection can let us think this PHY can be configured to fit other purposes. But there are reasons to think the SATA mode will be the only one usable: the PHY registers are only accessible indirectly through two registers in the SATA range, the PHY seems to be integrated and no information tells us the contrary. For these reasons, make the driver a SATA PHY driver. Signed-off-by:

Since the USB 2.0 PHYs are required with EHCI/OHCI USB drivers and USB gadget controller supported by the DWC2 gadget driver, make it depend on them and default to ARCH_EXYNOS as they are meant for Exynos platforms.
