When an rc device is created, we do not know what key codes it will support, since a new keymap might be loaded at some later point. So, we set all keybit in the input device. The uevent for the input device includes all the key codes, of which there are now 768. This overflows the size of the uevent (UEVENT_BUFFER_SIZE) and no event is generated. Revert for now until we figure out a different solution. This reverts commit fec225a0. Cc: <stable@vger.kernel.org> # 4.20+ Reported-by:

There are lots of warnings produced by this driver. It is not as much as atomisp, but it is still a lot. So, use the same solution to hide most of them. Those need to be fixed before promoting it out of staging, so add it at the TODO list. Signed-off-by: -

Commit 5964cbd8 ("imx: Set capture compose rectangle in capture_device_set_format") broke the compilation of commit 05f63404 ("staging/imx7: add imx7 CSI subdev driver"). These patches came in through different pull requests and nobody noticed that the first changed functions that the second relied upon. Update imx7-media-csi.c accordingly. Signed-off-by:

The runtime PM of this device is enabled after v4l2_ctrl_handler_setup(), and this makes this device's runtime PM usage count a negative value. The ov7740_set_ctrl() tries to do something only if the device's runtime PM usage counter is nonzero. ov7740_set_ctrl() { if (!pm_runtime_get_if_in_use(&client->dev)) return 0; <do something>; pm_runtime_put(&client->dev); return ret; } However, the ov7740_set_ctrl() is called by v4l2_ctrl_handler_setup() while the runtime PM of this device is not yet enabled. In this case, the pm_runtime_get_if_in_use() returns -EINVAL (!= 0). Therefore we can't bail out of this function and the usage count is decreased by pm_runtime_put() without increment. This fixes this problem by enabling the runtime PM of this device before v4l2_ctrl_handler_setup() so that the ov7740_set_ctrl() is always called when the runtime PM is enabled.

The check to see if type is V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE is redundant as this has been already checked at the start of the function and if it's not that value then -ENOSYS is returned. Hence the sprintf can be replaced by a simpler string copy. Detected by CoverityScan, CID#1309450 ("Logically dead code") Signed-off-by:Colin Ian King <colin.king@canonical.com> Signed-off-by:

This commit changes the return type of mem2mem buffer handling API. Namely, these functions: v4l2_m2m_next_buf v4l2_m2m_last_buf v4l2_m2m_buf_remove v4l2_m2m_next_src_buf v4l2_m2m_next_dst_buf v4l2_m2m_last_src_buf v4l2_m2m_last_dst_buf v4l2_m2m_src_buf_remove v4l2_m2m_dst_buf_remove which currently return void pointer. In every case, the actual return type is a struct vb2_v4l2_buffer pointer. Change the return type of the listed functions, so type checking can be properly used. Signed-off-by:

The CSI controller can take raw data from the data bus and output it directly to capture buffers. This can be used to support the JPEG media bus format. While the controller can report minimum and maximum bytes per line, it has no way to report how many lines were captured in the last frame. Thus, even when the on-bus data is framed correctly, we have no way to accertain the actual amount of data captured, unless we scan the buffer for JPEG EOI markers, or sequential zeros. For now we leave bytesused alone, and leave it up to userspace applications to parse the data. Signed-off-by:

max_register is currently set to 0x1000. This is beyond the mapped address range of the hardware, so attempts to dump the regmap from debugfs would trigger a kernel exception. Furthermore, the useful registers only occupy a small section at the beginning of the full range. Change the value to 0x9c, the last known register on the V3s and H3. On the A31, the register range is extended to support additional capture channels. Since this is not yet supported, ignore it for now.
