media: omap3isp: Ignore failure of stopping streaming on external subdev

2020-01-03T15:35:01Z

The isp was marked to have failed to stop if stopping streaming on an external subdev failed. The return value from the external subdev should be ignored instead as it is not part of the ISP and thus the ISP does not need to be reset for that reason.

media: omap3isp: Don't set streaming state on random subdevs

2019-08-15T11:07:04Z

The streaming state should be set to the first upstream sub-device only, not everywhere, for a sub-device driver itself knows how to best control the streaming state of its own upstream sub-devices. Signed-off-by: Sakari Ailus Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: Remove dev_err() usage after platform_get_irq()

2019-08-07T20:08:33Z

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // While we're here, remove braces on if statements that only have one statement (manually).

media: omap3isp: Rework OF endpoint parsing

2019-07-25T14:59:49Z

Rework OF endpoint parsing for the omap3isp driver. This does add some lines of code. The benefits are still clear: - the great complication related to callbacks in endpoint parsing is gone; instead endpoints are obtained port by port and - endpoints may now have a default bus configuration which was not possible while using callbacks. This driver does not benefit from that feature, but as the omap3isp is one of the exemplary drivers, this works as an example for driver developers.

media: omap3isp: Don't rely on devm for memory resource management

2019-05-29T20:39:52Z

devm functions are fine for managing resources that are directly related to the device at hand and that have no other dependencies. However, a process holding a file handle to a device created by a driver for a device may result in the file handle left behind after the device is long gone. This will result in accessing released (and potentially reallocated) memory. Instead, manage the memory resources in the driver. Releasing the resources can be later on bound to e.g. by releasing a reference. Signed-off-by: Sakari Ailus Acked-by: Hans Verkuil Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab
