| * usb: cdns3: gadget: own the lock wrongly at the suspend routinePeter Chen2020-10-301-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the system goes to suspend, if the controller is at device mode with cable connecting to host, the call stack is: cdns3_suspend-> cdns3_gadget_suspend -> cdns3_disconnect_gadget, after cdns3_disconnect_gadget is called, it owns lock wrongly, it causes the system being deadlock after resume due to at cdns3_device_thread_irq_handler, it tries to get the lock, but can't get it forever. To fix it, we delete the unlock-lock operations at cdns3_disconnect_gadget, and do it at the caller.

| * usb: cdns3: Fix on-chip memory overflow issuePawel Laszczak2020-10-303-76/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch fixes issue caused setting On-chip memory overflow bit in usb_sts register. The issue occurred because EP_CFG register was set twice before USB_STS.CFGSTS was set. Every write operation on EP_CFG.BUFFERING causes that controller increases internal counter holding the number of reserved on-chip buffers. First time this register was updated in function cdns3_ep_config before delegating SET_CONFIGURATION request to class driver and again it was updated when class wanted to enable endpoint. This patch fixes this issue by configuring endpoints enabled by class driver in cdns3_gadget_ep_enable and others just before status stage.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Bastien Nocera <hadess@hadess.net> Contrary to the comment above the id table, we didn't implement a match function. This meant that every single Apple device that was already plugged in to the computer would have its device driver reprobed when the apple-mfi-fastcharge driver was loaded, eg. the SD card reader could be reprobed when the apple-mfi-fastcharge after pivoting root during boot up and the module became available. Make sure that the driver probe isn't being run for unsupported devices by adding a match function that checks the product ID, in addition to the id_table checking the vendor ID.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Bastien Nocera <hadess@hadess.net> When a USB device driver has both an id_table and a match() function, make sure to check both to find a match, first matching the id_table, then checking the match() function. This makes it possible to have module autoloading done through the id_table when devices are plugged in, before checking for further device eligibility in the match() function.

This has been reported on some samples of the Odroid-N2 using the Combee II Zibgee USB dongle. > struct acm *acm = container_of(work, struct acm, work) is incorrect in case of a delayed work and causes warnings, usually from the workqueue: > WARNING: CPU: 0 PID: 0 at kernel/workqueue.c:1474 __queue_work+0x480/0x528. When this happens, USB eventually stops working completely after a while. Also the ACM_ERROR_DELAY bit is never set, so the cooldown mechanism previously introduced cannot be triggered and acm_submit_read_urb() is never called. This changes makes the cdc-acm driver use a single delayed work, fixing the pointer arithmetic in acm_softint() and set the ACM_ERROR_DELAY when the cooldown mechanism appear to be needed.

The point of using [] instead of [0] is that with [] the compiler will generate a build warning if it isn't the last member of a struct.

But i2c_acpi_install_space_handler() had a call to acpi_walk_dep_device_list() hidden (that is I missed it) at the end of it, so as an unwanted side-effect now acpi_walk_dep_device_list() was also being called before i2c_acpi_register_devices(). Move the acpi_walk_dep_device_list() call to the end of i2c_acpi_register_devices(), so that it is once again called *after* the i2c_client-s hanging of the adapter have been created.

| * | | | | | | parisc: Add wrapper syscalls to fix O_NONBLOCK flag usageHelge Deller2020-10-232-7/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 75ae04206a4d ("parisc: Define O_NONBLOCK to become 000200000") changed the O_NONBLOCK constant to have only one bit set (like all other architectures). This change broke some existing userspace code (e.g. udevadm, systemd-udevd, elogind) which called specific syscalls which do strict value checking on their flag parameter. This patch adds wrapper functions for the relevant syscalls. The wrappers masks out any old invalid O_NONBLOCK flags, reports in the syslog if the old O_NONBLOCK value was used and then calls the target syscall with the new O_NONBLOCK value.

| * | | | | | | hil/parisc: Disable HIL driver when it gets stuckHelge Deller2020-10-223-8/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When starting a HP machine with HIL driver but without an HIL keyboard or HIL mouse attached, it may happen that data written to the HIL loop gets stuck (e.g. because the transaction queue is full). Usually one will then have to reboot the machine because all you see is and endless output of: Transaction add failed: transaction already queued? In the higher layers hp_sdc_enqueue_transaction() is called to queued up a HIL packet. This function returns an error code, and this patch adds the necessary checks for this return code and disables the HIL driver if further packets can't be sent. Tested on a HP 730 and a HP 715/64 machine. Signed-off-by: Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org>
| * | | | | | | parisc: Improve error return codes when setting rtc timeHelge Deller2020-10-221-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The HP 730 machine returned strange errors when I tried setting the rtc time. Add some debug code to improve the possibility to trace errors and document that hppa probably has as Y2k38 problem. Signed-off-by: Helge Deller <deller@gmx.de>
