'usb_free_urb(urb)' is a no-op, because urb is known to be NULL. It is likelly that releasing resources allocated by 'tm6000_alloc_urb_buffers()' just a few lines above is expected here. This has been spotted by the following coccinelle script: @@ expression ret, x, e; identifier f; @@ * if (x == NULL) { ... when != x = e; ( * f(<+...x...+>); | * ret = f(<+...x...+>); ) ... } Signed-off-by:Christophe JAILLET <christophe.jaillet@wanadoo.fr> 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. Before this patch: $ modinfo drivers/media/i2c/et8ek8/et8ek8.ko | grep alias alias: i2c:et8ek8 After this patch: $ modinfo drivers/media/i2c/et8ek8/et8ek8.ko | grep alias alias: i2c:et8ek8 alias: of:N*T*Ctoshiba,et8ek8C* alias: of:N*T*Ctoshiba,et8ek8 Signed-off-by:

Declare stv0299_config structures as const as they are only passed as an argument to the function dvb_attach. dvb_attach calls its first argument on the rest of its arguments.

There is an exit path where rx is kfree'd on put_ir_rx and then a jump to label out_put_xx will again kfree it with another call to put_ir_rx.

Some WPF instances, on Gen3 devices, can perform 90° rotation when writing frames to memory. Implement support for this using the V4L2_CID_ROTATE control. Signed-off-by:
-
Laurent Pinchart authored
V4L2 exposes parameters that influence buffers sizes through the format ioctls (VIDIOC_G_FMT, VIDIOC_TRY_FMT, VIDIOC_S_FMT, and possibly VIDIOC_G_SELECTION and VIDIOC_S_SELECTION). Other parameters not part of the format structure may also influence buffer sizes or buffer layout in general. One existing such parameter is rotation, which is implemented by the V4L2_CID_ROTATE control and thus exposed through the V4L2 control ioctls. The interaction between those parameters and buffers is currently only partially specified by the V4L2 API. In particular interactions between controls and buffers isn't specified at all. The behaviour of the VIDIOC_S_FMT and VIDIOC_S_SELECTION ioctls when buffers are allocated is also not fully specified. This patch clearly defines and documents the interactions between formats, selections, controls and buffers. The preparatory discussions for the documentation change considered completely disallowing controls that change the buffer size or layout, in favour of extending the format API with a new ioctl that would bundle those controls with format information. The idea has been rejected, as this would essentially be a restricted version of the upcoming request API that wouldn't bring any additional value. Another option we have considered was to mandate the use of the request API to modify controls that influence buffer size or layout. This has also been rejected on the grounds that requiring the request API to change rotation even when streaming is stopped would significantly complicate implementation of drivers and usage of the V4L2 API for applications. Applications will however be required to use the upcoming request API to change at runtime formats or controls that influence the buffer size or layout, because of the need to synchronize buffers with the formats and controls. Otherwise there would be no way to interpret the content of a buffer correctly. Signed-off-by:
