2023-08-10media: cec-gpio: drop the cec_gpio_free callbackHans Verkuil1-6/+0
Since the CEC pin framework now keeps track of the interrupt and calls disable_irq when the kthread stops, there is no longer any need for the cec-gpio driver to do this in the free callback. So drop this code. Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2023-08-10media: cec-gpio: specify IRQF_NO_AUTOEN when requesting irqHans Verkuil1-3/+1
Use IRQF_NO_AUTOEN rather than manually disabling the requested interrupt. Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2023-04-11media: cec-gpio: Convert to platform remove callback returning voidUwe Kleine-König1-3/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2020-04-29media: cec-gpio: handle gpiod_get_value errors correctlyHans Verkuil1-7/+11
gpiod_get_value() can return negative values if an error occurs. In several places this error code was ignored. Ensure that errors codes are handled correctly throughout the CEC pin framework and CEC pin drivers. The return code of the cec_pin_ops read() callback had to be changed from 'bool' to 'int', which mean the prototype of that callback in the sun4i drm driver also had to be changed.

2020-04-15media: move CEC platform drivers to a separate directoryMauro Carvalho Chehab2-0/+300
As CEC support doesn't depend on MEDIA_SUPPORT, let's place the platform drivers outside the media menu. As a side effect, instead of depends on PCI, seco driver can select it (and DMI). Acked-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
