2025-05-01media: nxp: imx8-isi: better handle the m2m usage_countLaurentiu Palcu
Currently, if streamon/streamoff calls are imbalanced we can either end up with a negative ISI m2m usage_count (if streamoff() is called more times than streamon()) in which case we'll not be able to restart the ISI pipe next time, or the usage_count never gets to 0 and the pipe is never switched off. To avoid that, add a 'streaming' flag to mxc_isi_m2m_ctx_queue_data and use it in the streamon/streamoff to avoid incrementing/decrementing the usage_count uselessly, if called multiple times from the same context.

2025-04-30media: omap3isp: drop wait_prepare/finish callbacksHans Verkuil
Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish are NULL") it is no longer needed to set the wait_prepare/finish vb2_ops callbacks as long as the lock field in vb2_queue is set. Set the queue lock to &video->queue_lock, which makes it possible to drop the wait_prepare/finish callbacks. This simplifies the code and this is a step towards the goal of deleting these callbacks. Note that the lock field of struct video_device is never set in this driver, so the core v4l2_ioctl.c function v4l2_ioctl_get_lock() will never take a lock.

syzbot reported a uninit-value in cxusb_i2c_xfer. [1] Only when the write operation of usb_bulk_msg() in dvb_usb_generic_rw() succeeds and rlen is greater than 0, the read operation of usb_bulk_msg() will be executed to read rlen bytes of data from the dvb device into the rbuf. In this case, although rlen is 1, the write operation failed which resulted in the dvb read operation not being executed, and ultimately variable i was not initialized.

2025-04-25media: tw5864: Replace deprecated PCI functionsPhilipp Stanner
pcim_iomap_table() and pcim_iomap_regions() have been deprecated. pcim_iomap_regions(), furthermore, has so far wrongly been passed the device's name instead of the driver's name, which makes that function's debug prints useless. Replace the deprecated function with pcim_iomap_region(). Define the driver name globally and use it where appropriate.
