2021-10-25usb: gadget: uvc: implement dwPresentationTime and scrSourceClockMichael Olbrich
This patch adds the fields UVC_STREAM_PTS and UVC_STREAM_SCR to the uvc header, in case this data is available. It also enables the copy of the timestamp to the vb2_v4l2_buffer by setting V4L2_BUF_FLAG_TIMESTAMP_COPY in the queue.timestamp_flags.

2021-10-25usb:gadget: f_uac1: fixed sync playbackPavel Hofman
The u_audio param fb_max was not set to its default value in f_uac1.c. As a result the maximum value of Playback Pitch ctl was kept at 1000000, not allowing to set faster playback pitch for UAC1. The setting required moving the default constant UAC2_DEF_FB_MAX from u_uac2.h to FBACK_FAST_MAX in u_audio.h as that header is common for f_uac1.c and f_uac2.c.

2021-10-22usb: dwc3: gadget: Skip resizing EP's TX FIFO if already resizedJack Pham
Some functions may dynamically enable and disable their endpoints regularly throughout their operation, particularly when Set Interface is employed to switch between Alternate Settings. For instance the UAC2 function has its respective endpoints for playback & capture associated with AltSetting 1, in which case those endpoints would not get enabled until the host activates the AltSetting. And they conversely become disabled when the interfaces' AltSetting 0 is chosen. With the DWC3 FIFO resizing algorithm recently added, every usb_ep_enable() call results in a call to resize that EP's TXFIFO, but if the same endpoint is enabled again and again, this incorrectly leads to FIFO RAM allocation exhaustion as the mechanism did not account for the possibility that endpoints can be re-enabled many times. Example log splat: dwc3 a600000.dwc3: Fifosize(3717) > RAM size(3462) ep3in depth:217973127 configfs-gadget gadget: u_audio_start_capture:521 Error! dwc3 a600000.dwc3: request 000000000be13e18 was not queued to ep3in Add another bit DWC3_EP_TXFIFO_RESIZED to dep->flags to keep track of whether an EP had already been resized in the current configuration. If so, bail out of dwc3_gadget_resize_tx_fifos() to avoid the calculation error resulting from accumulating the EP's FIFO depth repeatedly. This flag is retained across multiple ep_disable() and ep_enable() calls and is cleared when GTXFIFOSIZn is reset in dwc3_gadget_clear_tx_fifos() upon receiving the next Set Config.

musb_gadget_queue() adds the passed request to musb_ep::req_list. If the endpoint is idle and it is the first request then it invokes musb_queue_resume_work(). If the function returns an error then the error is passed to the caller without any clean-up and the request remains enqueued on the list. If the caller enqueues the request again then the list corrupts. Remove the request from the list on error.

2021-10-21usb: max-3421: Use driver data instead of maintaining a list of bound devicesUwe Kleine-König
Instead of maintaining a single-linked list of devices that must be searched linearly in .remove() just use spi_set_drvdata() to remember the link between the spi device and the driver struct. Then the global list and the next member can be dropped. This simplifies the driver, reduces the memory footprint and the time to search the list. Also it makes obvious that there is always a corresponding driver struct for a given device in .remove(), so the error path for !max3421_hcd can be dropped, too. As a side effect this fixes a data inconsistency when .probe() races with itself for a second max3421 device in manipulating max3421_hcd_list. A similar race is fixed in .remove(), too.

In case of USB_DR_MODE_PERIPHERAL, the OTG clock is disabled at the end of the probe (it is not the case if USB_DR_MODE_HOST or USB_DR_MODE_OTG). The clock is then enabled on udc_start. If dwc2_drd_role_sw_set is called before udc_start (it is the case if the usb cable is plugged at boot), GOTGCTL and GUSBCFG registers cannot be read/written, so session cannot be overridden.

2021-10-21usb: ohci: disable start-of-frame interrupt in ohci_rh_suspendYinbo Zhu
While going into S3 or S4 suspend, an OHCI host controller can generate interrupt requests if the INTR_SF enable flag is set. The interrupt handler routine isn't prepared for this and it doesn't turn off the flag, causing an interrupt storm. To fix this problem, make ohci_rh_suspend() always disable INTR_SF interrupts after processing the done list and the ED unlinks but before the controller goes into the suspended (non-UsbOperational) state. There's no reason to leave the flag enabled, since a suspended controller doesn't generate Start-of-Frame packets.

2021-10-17brd: reduce the brd_devices_mutex scopeTetsuo Handa
As with commit 8b52d8be86d72308 ("loop: reorder loop_exit"), unregister_blkdev() needs to be called first in order to avoid calling brd_alloc() from brd_probe() after brd_del_one() from brd_exit(). Then, we can avoid holding global mutex during add_disk()/del_gendisk() as with commit 1c500ad706383f1a ("loop: reduce the loop_ctl_mutex scope").

2021-10-15Input: touchscreen - avoid bitwise vs logical OR warningNathan Chancellor
A new warning in clang points out a few places in this driver where a bitwise OR is being used with boolean types: drivers/input/touchscreen.c:81:17: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical] data_present = touchscreen_get_prop_u32(dev, "touchscreen-min-x", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This use of a bitwise OR is intentional, as bitwise operations do not short circuit, which allows all the calls to touchscreen_get_prop_u32() to happen so that the last parameter is initialized while coalescing the results of the calls to make a decision after they are all evaluated. To make this clearer to the compiler, use the '|=' operator to assign the result of each touchscreen_get_prop_u32() call to data_present, which keeps the meaning of the code the same but makes it obvious that every one of these calls is expected to happen.
