media: tegra_cec: fix the return value handle for platform_get_irq()

2023-08-10T05:58:36Z

There is no possible for platform_get_irq() to return 0, and the return value of platform_get_irq() is more sensible to show the error reason. Signed-off-by: Ruan Jinjie Signed-off-by: Hans Verkuil

media: cec: tegra: drop of_match_ptr for ID table

2023-07-14T10:32:24Z

The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might not be relevant here). This also fixes !CONFIG_OF error: drivers/media/cec/platform/tegra/tegra_cec.c:457:34: error: ‘tegra_cec_of_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski Reviewed-by: Hans Verkuil Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: tegra_cec: Convert to platform remove callback returning void

2023-04-11T14:59:14Z

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. Signed-off-by: Uwe Kleine-König Signed-off-by: Hans Verkuil

media: tegra-cec: Handle errors of clk_prepare_enable()

2021-08-04T12:43:52Z

tegra_cec_probe() and tegra_cec_resume() ignored possible errors of clk_prepare_enable(). The patch fixes this. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Evgeny Novikov Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: cec: rename CEC platform drivers config options

2020-04-15T10:25:20Z

Most CEC platform drivers are using VIDEO_*_CEC pattern, some with an _HDMI extension too. Well, they're not related to V4L2 support, and we don't really need those big config names. So drop VIDEO_* from them, remove _HDMI (if present) and move CEC to the start. This way, all platform driver options are now CEC_. Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: move CEC platform drivers to a separate directory

2020-04-15T10:06:40Z

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 Signed-off-by: Mauro Carvalho Chehab
