media: cec: Fix debugfs leak on bus_register() failure

2025-10-14T13:07:37+00:00

In cec_devnode_init(), the debugfs directory created with debugfs_create_dir() is not removed if bus_register() fails. This leaves a stale "cec" entry in debugfs and prevents proper module reloading. Fix this by removing the debugfs directory in the error path.

media: remove unneeded 'fast_io' parameter in regmap_config

2025-08-29T09:04:02+00:00

When using MMIO with regmap, fast_io is implied. No need to set it again. Signed-off-by: Wolfram Sang Signed-off-by: Hans Verkuil

media: cec: extron-da-hd-4k-plus: drop external-module make commands

2025-08-29T09:04:02+00:00

Delete the external-module style Makefile commands. They are not needed for in-tree modules. This is the only Makefile in the kernel tree (aside from tools/ and samples/) that uses this Makefile style. The same files are built with or without this patch.

media: v4l2: Rename second ioctl handlers argument to 'void *priv'

2025-08-13T06:34:01+00:00

The second argument to the ioctl handlers is not a file handle any more. The standard practice is to name it 'void *priv' in drivers. Many drivers still name it 'void *fh', and a few use more exotic names. Replace those more exotic names with 'void *priv' in all media drivers.

media: cec: cec-gpio: reading hpd/5v is allowed to sleep

2025-07-08T06:35:27+00:00

Reading the hpd or 5v gpios is something that can sleep, so rework the code to allow this. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: cec: cec-gpio: rename functions

Ensure that the interrupt function names clearly state for which gpio they are (cec/hpd/5v). No functional changes. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: cec: core: add rx-no-low-drive setting

2025-07-08T06:35:26+00:00

If rx-no-low-drive is set, then the CEC pin framework will disable the detection of situations where a Low Drive has to be generated. So if this is set, then we will never generate Low Drives. This helps testing whether other CEC devices generate Low Drive pulses by ensuring it is not us that is generating them. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: cec: core: add glitch error injection

2025-07-08T06:35:26+00:00

This adds support for inserting 'glitches' after a falling and/or rising edge. This tests what happens when there are little voltage spikes after falling or rising edges, which can be caused due to noise or reflections on the CEC line. A proper CEC implementation will deglitch this, but a poor implementation can create a Low Drive pulse in response, effectively making CEC unusable.
