media: i2c: imx415: Release runtime PM reference on VBLANK error

2026-08-06T10:24:26+00:00

The VBLANK path returned immediately when programming VMAX failed after pm_runtime_get_if_in_use() had taken a runtime PM reference. Break out of the switch instead so the common pm_runtime_put() path is used.

media: i2c: imx415: Return test pattern write errors

2026-08-06T10:24:26+00:00

imx415_set_testpattern() accumulates failures from cci_write(), but drops the value and always returns success. Return the accumulated error so V4L2 reports failures to userspace.

media: i2c: imx471: Fix uninitialized error value in imx471_set_ctrl()

2026-07-29T22:05:38+00:00

The exposure and vertical blanking writes pass the address of the local ret variable to cci_write() as its error pointer, but there is no earlier error to propagate: each case is a single standalone write, like the other controls in the same switch that already pass NULL. In the exposure case ret is still uninitialized, so a non-zero stack value makes cci_write() return early without programming the register, and the control write reports a bogus status. The vertical blanking case is benign today because ret is zero there, but the construct is equally wrong. Pass NULL as the error pointer in both cases.

media: i2c: cvs: Pass link frequency explicitly to csi_set_link_cfg()

2026-07-29T12:57:06+00:00

The link frequency, retrieved in cvs_csi_enable_streams(), is stored in the icvs structure to then be used right after in csi_set_link_cfg(), called only from the same function. Pass it as a function parameter instead to improve readability. Signed-off-by: Laurent Pinchart Tested-by: Antti Laakso Signed-off-by: Sakari Ailus

media: i2c: mt9t112: fix incorrect PTR_ERR() call on non-error pointer

2026-07-29T12:55:47+00:00

In mt9t112_probe(), the clock error check after devm_v4l2_sensor_clk_get() calls PTR_ERR(priv->clk) unconditionally, before testing IS_ERR(). On a successful lookup, priv->clk is a valid pointer and calling PTR_ERR() on it is incorrect API usage. While the comparison against -ENOENT happens to be harmless in practice (valid kernel pointers never fall in the error range), this is still a violation of the IS_ERR()/PTR_ERR() contract that can mislead readers. Restructure the check to guard PTR_ERR() inside IS_ERR(), using the simpler != -ENOENT form to avoid an unnecessary else clause. Signed-off-by: Uday Khare Signed-off-by: Sakari Ailus

media: i2c: ov9282: restore flash duration calculation

2026-07-29T12:55:47+00:00

The migration to CCI helpers made V4L2_CID_FLASH_DURATION write the requested duration directly to OV9282_REG_STROBE_FRAME_SPAN, dropping the conversion from microseconds to the register value. This made flash strobes too long and produced overly bright frames. Restore the missing calculation so flash duration is programmed correctly again.

This also removes initializing reg_write to NULL, which will help with changing its signature in nvmem-provider[1]. Thanks to Sakari Ailus for their suggestion[2]!

Add 5 missing test patterns to complete the available hardware test patterns. The original mapping for color bars and solid color in the menu is preserved to prevent existing userspace application and automated vendor capture tests.
