If a lirc device is unplugged, the struct rc_dev is freed even though userspace can still have a file descriptor open on the lirc chardev. The rc_dev structure can be used in a subsequent, or even currently executing ioctl, read or write. Signed-off-by:

Split the protocol into two variants, one for keyboard and one for mouse data. Note that the mce_kbd protocol cannot be used on the igorplugusb, since the IR is too long. Signed-off-by:

The lirc keymap existed once upon a time to select the lirc protocol. Since '275ddb40 [media] rc-core: remove the LIRC "protocol"', IR is always passed to the lirc decoder so this keymap is no longer needed. Signed-off-by:

Adjust the keymap to use the correct nec scancodes, and adjust the rc driver to output the correct nec scancodes. Now the keymap can be used with any nec receiver, and the rc device should work with any nec keymap. Tested-by:

update_subrect() adjusts the sub-rectangle to be inside a base area. It checks width and height to not exceed those of the area, then it checks the low border (left or top) to lie within the area, then the high border (right or bottom) to lie there too. This latter check has a bug, which is fixed by this patch. Signed-off-by:

v4l2_subdev_{core/video}_ops structures are stored in the fields of the v4l2_subdev_ops structure which are of type const.

After changes to v4l2_clk API introduced in v4.1 by commits a37462b9 '[media] V4L: remove clock name from v4l2_clk API' and 4f528afc '[media] V4L: add CCF support to the v4l2_clk API', ov6650 sensor stopped responding because v4l2_clk_get(), still called with depreciated V4L2 clock name "mclk", started to return respective CCF clock instead of the V4l2 one registered by soc_camera. Fix it by calling v4l2_clk_get() with NULL clock name. Created and tested on Amstrad Delta against Linux-4.7-rc3 with omap1_camera fixes. Signed-off-by:

The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF. Signed-off-by:

The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed. But in order to change how the core reports modaliases to user-space, it's better to export it.

Several error paths didn't log why an error was returned. Add this.

The CEC_TRANSMIT ioctl now returns -EPERM if an attempt is made to transmit a message for an unconfigured adapter (i.e. userspace never called CEC_ADAP_S_LOG_ADDRS).

The CEC specifications explicitly allows you to send poll messages and Image/Text View On messages to a TV, even when unconfigured (i.e. there is no hotplug signal detected). Some TVs will pull the HPD low when switching to another input, or when going into standby, but CEC should still be allowed to wake up such a display. Add support for sending messages with initiator 0xf (Unregistered) and destination 0 (TV) when no physical address is present. This also required another change: the CEC adapter has to stay enabled as long as 1) the CEC device is configured or 2) at least one filehandle is open for the CEC device. Signed-off-by:
