2024-10-12media: Switch back to struct platform_driver::remove()Uwe Kleine-König1-1/+1
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/media to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2023-08-10media: tegra_cec: fix the return value handle for platform_get_irq()Ruan Jinjie1-2/+2
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 <ruanjinjie@huawei.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
2023-07-14media: cec: tegra: drop of_match_ptr for ID tableKrzysztof Kozlowski1-1/+1
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 <krzysztof.kozlowski@linaro.org> Reviewed-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
2023-04-11media: tegra_cec: Convert to platform remove callback returning voidUwe Kleine-König1-4/+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.

2021-08-04media: tegra-cec: Handle errors of clk_prepare_enable()Evgeny Novikov1-4/+6
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).

2020-04-15media: cec: rename CEC platform drivers config optionsMauro Carvalho Chehab1-1/+1
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_<driver>.

2020-04-15media: move CEC platform drivers to a separate directoryMauro Carvalho Chehab3-0/+599
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).
