2023-10-12media: cadence: csi2rx: Add get_fmt and set_fmt pad opsPratyush Yadav1-1/+95
The format is needed to calculate the link speed for the external DPHY configuration. It is not right to query the format from the source subdev. Add get_fmt and set_fmt pad operations so that the format can be configured and correct bpp be selected. Initialize and use the v4l2 subdev active state to keep track of the active formats. Also propagate the new format from the sink pad to all the source pads.

2023-10-12media: cadence: csi2rx: Unregister v4l2 async notifierPratyush Yadav1-1/+6
The notifier is added to the global notifier list when registered. When the module is removed, the struct csi2rx_priv in which the notifier is embedded, is destroyed. As a result the notifier list has a reference to a notifier that no longer exists. This causes invalid memory accesses when the list is iterated over. Similar for when the probe fails. Unregister and clean up the notifier to avoid this.

2023-10-07media: imon: fix access to invalid resource for the second interfaceTakashi Iwai1-0/+6
imon driver probes two USB interfaces, and at the probe of the second interface, the driver assumes blindly that the first interface got bound with the same imon driver. It's usually true, but it's still possible that the first interface is bound with another driver via a malformed descriptor. Then it may lead to a memory corruption, as spotted by syzkaller; imon driver accesses the data from drvdata as struct imon_context object although it's a completely different one that was assigned by another driver. This patch adds a sanity check -- whether the first interface is really bound with the imon driver or not -- for avoiding the problem above at the probe time.

When building the modules 'modpost' warns about missing MODULE_DESCRIPTION. Since almost none of the rc keymap modules have this, it produces a lot of warnings. As a first step to fixing all media modules, add this line to all keymaps. The description should be a human-readable string describing the remote or the remote controller that the keymap can be used with. Note that keymaps/rc-cec.c is actually compiled into the rc-core, so that is the sole keymap source that didn't need this.
