[ Upstream commit 6348be02eead77bdd1562154ed6b3296ad3b3750 ] fdget() is the first thing done in scope, all matching fdput() are immediately followed by leaving the scope.

media: i2c: og01a1b: Fix V4L2 subdevice data initialization on probe

2026-05-23T11:04:28+00:00

[ Upstream commit 535b7f106991c7d8f0e5b8e1769bfb8b1ce9d3d6 ] It's necessary to finalize the camera sensor subdevice initialization on driver probe and clean V4L2 subdevice data up on error paths and driver removal. The change fixes a previously reported by v4l2-compliance issue of the failed VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT test: fail: v4l2-test-controls.cpp(1104): subscribe event for control 'User Controls' failed Fixes: 472377febf84 ("media: Add a driver for the og01a1b camera sensor") Signed-off-by: Vladimir Zapolskiy Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Sasha Levin

media: i2c: og01a1b: Replace client->dev usage

2026-05-23T11:04:28+00:00

[ Upstream commit 4d58f671944a16314f03d3c0c40ee69058ca02c9 ] The driver needs to access the struct device in many places, and retrieves it from the i2c_client itself retrieved with v4l2_get_subdevdata(). Store it as a pointer in struct og01a1b and access it from there instead, to simplify the driver. While at it, fix a mistake in the sort order of include statements.

media: i2c: ov08d10: fix image vertical start setting

2026-05-17T15:14:29+00:00

commit 5d150fa0f16096d736bd24d13e04495da5116fab upstream. The current settings for the "image vertical start" register appear to be incorrect. While this only results in an incorrect start line for native modes, this faulty setting causes actual problems in binning mode. At least on an i.MX8MP test system, only corrupted frames could be received. To correct this, the recommended settings from the reference register sets are used for all modes. Since this shifts the start by one line, the Bayer pattern also changes, which has also been corrected.

commit 8467c5ff5acae28513bc1e0af535e06b41b04344 upstream. Assert the reset GPIO before first power up. This avoids a mismatch where the first power up (when the reset GPIO defaults deasserted) differs from subsequent cycles.

media: dib8000: avoid division by 0 in dib8000_set_dds()

2026-05-17T15:14:29+00:00

commit dde3c37af95cd6fa301c4906f33d627bc9dd874c upstream. In dib8000_set_dds(), 1 << 26 (67108864) divided by e.g. 1 apparently can't fit into 16-bit variable unit_khz_dds_val, being truncated to 0; this will cause division by 0 while calling dprintk() with debugging enabled (via the module parameter). Use s32 instead of s16 to declare the variable, getting rid of the cast to u16 in the *else* branch as well...

commit d51c60a498e83c9a79884c8e420f97e3885c9583 upstream. Add checks for ioremap return values in saa7164_dev_setup(). If ioremap for BAR0 or BAR2 fails, release the already allocated PCI memory regions, remove the device from the global list, decrement the device count, and return -ENODEV. This prevents potential null pointer dereferences and ensures proper cleanup on memory mapping failures.

media: i2c: imx283: Fix hang when going from large to small resolution

2026-05-17T15:14:28+00:00

commit 9206359b2c396ff594adf39bc7daaadab0fcb367 upstream. When switching between modes (e.g. full resolution to binned), standby_cancel() previously cleared XMSTA (starting master mode data output) before the new mode's MDSEL, crop, and timing registers were programmed in start_streaming(). This caused the sensor to briefly output MIPI data using the previous mode's configuration. On receivers like imx-mipi-csis, this leads to FIFO overflow errors when switching from a higher to a lower resolution, as the receiver is configured for the new smaller frame size but receives stale full-resolution data. Fix this by moving the XMSTA and SYNCDRV register writes from standby_cancel() to the end of start_streaming(), after all mode, crop, and timing registers have been configured. Also explicitly stop master mode (XMSTA=1) when stopping the stream, matching the pattern used by other Sony sensor drivers (imx290, imx415). Use named macros IMX283_XMSTA_START/STOP instead of raw 0/BIT(0) for readability.
