When the driver fails to call the dma_set_mask(), the driver will get the following splat: [ 55.853884] BUG: KASAN: use-after-free in __process_removed_driver+0x3c/0x240 [ 55.854486] Read of size 8 at addr ffff88810de60408 by task modprobe/590 [ 55.856822] Call Trace: [ 55.860327] __process_removed_driver+0x3c/0x240 [ 55.861347] bus_for_each_dev+0x102/0x160 [ 55.861681] i2c_del_driver+0x2f/0x50 This is because the driver has initialized the i2c related resources in cx23885_dev_setup() but not released them in error handling, fix this bug by modifying the error path that jumps after failing to call the dma_set_mask().

Add H264 level 1.0, 4.1, 4.2 to the list of supported formats. While the hardware does not fully support these levels, it does support most of them. The constraints on frame size and pixel formats already cover the limitation. This fixes negotiation of level on GStreamer 1.17.1.

The CODA960 manual states that ASO/FMO features of baseline are not supported, so for this reason this driver should only report constrained baseline support. This fixes negotiation issue with constrained baseline content on GStreamer 1.17.1. ASO/FMO features are unsupported for the encoder and untested for the decoder because there is currently no userspace support. Neither GStreamer parsers nor FFMPEG parsers support ASO/FMO.

The hardware is capable of encoding/decoding RGB and ARGB formats in whatever order the color components are, but the resulting jpegs look good if we start with raw data in BGR/ABGR order, so we will further only support V4L2_PIX_FMT_BGR24 and V4L2_PIX_FMT_ABGR32. Signed-off-by:

If the decoder prepare_run callback returns an error, the hardware is never started and v4l2_m2m_job_finish() is called immediately, currently in every error path. Remove the duplicated job_finish calls from the error paths and reuse the v4l2_m2m_job_finish() at the end of coda_pic_run_work instead. Signed-off-by:

Video decoder driver auto-suspends the hardware if there is no exchange of command or response for certain amount of time. In auto suspended state, it becomes mandatory to power on the hardware before requesting it to process a command. The fix ensures the hardware is powered on during stop streaming. Signed-off-by:

During reconfig (DRC) event from firmware, it is not guaranteed that all the DPB(internal) buffers would be released by the firmware. Some buffers might be released gradually while processing frames from the new sequence. These buffers now stay idle in the dpblist. In subsequent call to queue the DPBs to firmware, these idle buffers should not be queued. The fix identifies those buffers and free them. Signed-off-by:

If venus_probe fails at pm_runtime_put_sync the error handling first calls hfi_destroy and afterwards hfi_core_deinit. As hfi_destroy sets core->ops to NULL, hfi_core_deinit cannot call the core_deinit function anymore. Avoid this null pointer derefence by skipping the call when necessary. Signed-off-by:

An not calibrated x_start setting would result in an incorrect AWB grid configuration on a sensor when only the rightmost stripe is used. If the AWB grid coordinate is set to the rightmost stripe, for example, x_start is greater than 640, the AWB grid will be at the rightmost edge of the sensor. The AWB statistic will be fetched from the wrong place of the sensor and results in an incorrect AWB estimation result. Therefore, stripe offset should subtract from x_start to have a correct grid configuration for the rightmost stripe. Signed-off-by:

The only effect of returning an error code in an i2c remove callback is that the i2c core emits a generic warning and still removes the device. So even if disabling the regulator fails it's sensible to further cleanup and then return zero to only emit a single error message. This patch is a preparation for making i2c remove callbacks return void. Signed-off-by:
