The priv field of struct v4l2_pix_format shouldn't be set by drivers, it's set by the v4l2 core instead to V4L2_PIX_FMT_PRIV_MAGIC. Drop this from the few media drivers that still do this. Note that the gspca patch is slightly more involved since some of the sub-gspca drivers use the priv field internally. Signed-off-by:

When reaching the end of stream, V4L2 m2m clients may expect the V4L2_EOS_EVENT. Although the V4L2_EOS_EVENT is deprecated behavior, drivers must signal that event before dequeuing the buffer that has the V4L2_BUF_FLAG_LAST flag set. If a driver queues the V4L2_EOS_EVENT event and returns the buffer after the check for events but before the check for buffers, vb2_m2m_poll() will signal that the buffer with V4L2_BUF_FLAG_LAST can be read but not that the V4L2_EOS_EVENT is available. Split the check for buffers into a separate function and check for available buffers before checking for events. This ensures that if vb2_m2m_poll() signals POLLIN | POLLRDNORM for the V4L2_BUF_FLAG_LAST buffer, it signals POLLPRI for the V4L2_EOS_EVENT, too. Signed-off-by:

When reaching the end of stream, V4L2 clients may expect the V4L2_EOS_EVENT before being able to dequeue the last buffer, which has the V4L2_BUF_FLAG_LAST flag set. If the vb2_poll() function first checks for events and afterwards if buffers are available, a driver can queue the V4L2_EOS_EVENT event and return the buffer after the check for events but before the check for buffers. This causes vb2_poll() to signal that the buffer with V4L2_BUF_FLAG_LAST can be read without the V4L2_EOS_EVENT being available. First, check for available buffers and afterwards for events to ensure that if vb2_poll() signals POLLIN | POLLRDNORM for the V4L2_BUF_FLAG_LAST buffer, it also signals POLLPRI for the V4L2_EOS_EVENT.

This driver set the colorspace to SRGB, but that makes no sense for a touchscreen. Use RAW instead. This also ensures consistency with the v4l_pix_format_touch() call that's used in v4l2-ioctl.c. Signed-off-by:

The T230C v2 hardware needs a mode of the si2168 chip to be set for which the si2168 driver previously had no support. This patch uses a specific measure to configure this on the T230C v2 hardware only - see the flag passed via the ts_mode attribute and its dependency on USB_PID_MYGICA_T230C2. Signed-off-by:

This patch schedules a USB reset device call following a USB clear halt error. The issues solved, and patch implementation, are similar to those found in drivers/hid/usbhid/hid-core.c. As seen on very rare occasions approximately one time per month (mceusb device 2304:0225 in this sample) Jul 27 2018 15:09:39 [59388.696941] mceusb 1-1.1.2:1.0: Error: urb status = -32 (RX HALT) [59388.698838] mceusb 1-1.1.2:1.0: rx clear halt error -32 the device can get into RX or TX HALT state where usb_clear_halt() also fails and also returns -EPIPE (HALT/STALL). After which, all further mceusb device control and data I/O always fail with HALT/STALL. Subsequently, the entire mceusb device no longer functions. Cause and problem replication conditions remain unknown. Further troubleshooting reveals usb_reset_device() restores mceusb device operation. Patch test 1: Hot unplugging the mceusb device triggers USB RX HALT and USB clear halt errors. A mceusb_dev_disconnect() call follows unplug. This patch's reset device call invokes an extra mceusb_dev_probe() mceusb_dev_disconnect() cycle, before the mceusb driver detaches. The additional probe/disconnect verifies the patch's device reset code executed. But note this patch is for USB clear halt error cases not caused by unplugging the mceusb device. Patch test 2: Simulate a RX HALT and a clear halt error with instrumented code in the driver. Jul 12 2019 19:41:18 [522745.263104] mceusb 1-1.3:1.0: set rx halt retval, 0 [522745.263943] mceusb 1-1.3:1.0: Error: rx urb status = -32 (RX HALT) [522745.263970] mceusb 1-1.3:1.0: kevent 1 scheduled [522745.264016] mceusb 1-1.3:1.0: kevent handler called (flags 0x2) [522745.272883] mceusb 1-1.3:1.0: rx clear halt status = 0 [522745.272917] mceusb 1-1.3:1.0: stuck RX HALT state requires USB Reset Device to clear [522745.273005] mceusb 1-1.3:1.0: mceusb_dev_disconnect called [522745.702815] usb 1-1.3: reset full-speed USB device number 14 using dwc_otg [522745.836812] mceusb 1-1.3:1.0: mceusb_dev_probe called [522745.836823] mceusb 1-1.3:1.0: acceptable bulk inbound endpoint found [522745.836832] mceusb 1-1.3:1.0: acceptable bulk outbound endpoint found ... The result matches what is expected when the device gets into a real rx clear halt error case by itself. This is the same sequence of messages when manually invoking the ./usbreset command line utility with an unpatched mceusb driver. Signed-off-by:

When CONFIG_DVB_DIB9000 is disabled, we can still compile code that now fails to link against dibx000_i2c_set_speed: drivers/media/usb/dvb-usb/dib0700_devices.o: In function `dib01x0_pmu_update.constprop.7': dib0700_devices.c:(.text.unlikely+0x1c9c): undefined reference to `dibx000_i2c_set_speed' The call sites are both through dib01x0_pmu_update(), which gets passed an 'i2c' pointer from dib9000_get_i2c_master(), which has returned NULL. Checking this pointer seems to be a good idea anyway, and it avoids the link failure in most cases. Sean Young found another case that is not fixed by that, where certain gcc versions leave an unused function in place that causes the link error, but adding an explict IS_ENABLED() check also solves this.
