[media] usbvision: move init code to probe()

2015-08-11T09:55:26Z

These things are only initialized if you start streaming video, but they are also used in the disconnect function. So just init them always during probe time. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] usbvision: fix DMA from stack warnings

2015-08-11T09:54:22Z

In various places the stack was used to provide buffers for USB data, but this should be allocated memory. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] usbvision: remove power_on_at_open and timed power off

2015-08-11T09:49:17Z

This causes lots of problems and is *very* slow as well. One of the main problems is that this prohibits the use of the control framework since subdevs will be unloaded on power off which is not allowed as long as they are used by a usb device. Apparently the reason for doing this is to turn off a noisy tuner. My hardware has no problem with that, and I wonder whether the hardware with that noisy tuner wasn't just functioning improperly as I have never heard of noisy tuners. Contact me if you have one of those devices and I can take a look whether the tuner can't be powered off if necessary by letting the tuner subdevice go into standby mode. Unloading the tuner module is just evil and is not the right approach. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] usbvision: Use setup_timer

2015-01-27T12:08:03Z

Convert a call to init_timer and accompanying intializations of the timer's data and function fields to a call to setup_timer. A simplified version of the semantic match that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // @@ expression t,f,d; @@ -init_timer(&t); +setup_timer(&t,f,d); -t.data = d; -t.function = f; // The semantic patch also changes the cast to long to a cast to unsigned long in the data initializer, as unsigned long is the type of the data field.

[media] media: remove emacs editor variables

2014-12-22T19:52:20Z

1) This is not allowed by the kernel coding style 2) Just configure your editor correctly 3) It's really ugly Signed-off-by: Hans Verkuil Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] drivers/media/usb/usbvision/usbvision-core.c: Remove useless return variables

2014-07-04T18:35:02Z

This patch remove variables that are initialized with a constant, are never updated, and are only used as parameter of return. Return the constant instead of using a variable. Verified by compilation only. The coccinelle script that find and fixes this issue is: // @@ type T; constant C; identifier ret; @@ - T ret = C; ... when != ret when strict return - ret + C ; // Signed-off-by: Peter Senna Tschudin Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
