media: i2c: ov08d10: fix image vertical start setting

2026-05-17T15:13:45+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.

media: i2c: imx412: Assert reset GPIO during probe

2026-05-17T15:13:45+00:00

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.

commit f75e160745663ce9b13362ae6e90bd439c58df69 upstream. The control handler wasn't freed if adding controls failed, add an error exit label and convert the existing error return to use it.

media: i2c: imx219: Check return value of devm_gpiod_get_optional() in imx219_probe()

2026-05-17T15:13:27+00:00

commit 943b1f27a3eead21b22e2531a5432ea5910b60eb upstream. The devm_gpiod_get_optional() function may return an error pointer (ERR_PTR) in case of a genuine failure during GPIO acquisition, not just NULL which indicates the legitimate absence of an optional GPIO. Add an IS_ERR() check after the function call to catch such errors and propagate them to the probe function, ensuring the driver fails to load safely rather than proceeding with an invalid pointer.
