2012-03-19[media] V4L/v4l2-dev: Make 'videodev_init' as a subsys initcallBhupesh Sharma
As the V4L2 based UVC webcam gadget (g_webcam) expects the 'videodev' to present when the 'webcam_bind' routine is called, so 'videodev' should be available as early as possible. Now, when 'g_webcam' is built as a module (i.e. not a part of kernel) the late availability of 'videodev' is OK, but if 'g_webcam' is built statically as a part of the kernel, the kernel crashes (a sample crash dump using Designware 2.0 UDC is provided below). To solve the same, this patch makes 'videodev_init' as a subsys initcall.

2012-03-19[media] media, cx231xx: Fix double free on closeJesper Juhl
In cx231xx_v4l2_close() there are two calls to cx231xx_release_resources(dev) followed by kfree(dev). That is a problem since cx231xx_release_resources() already kfree()'s its argument, so we end up doing a double free. Easily resolved by just removing the redundant kfree() calls after the calls to cx231xx_release_resources(). I also changed the 'dev = NULL' assignments (which are rather pointless since 'dev' is about to go out of scope), to 'fh->dev = NULL' since it looks to me that that is what was actually intended. And I removed the 'dev = NULL' assignment at the end of cx231xx_release_resources() since it is pointless.

To avoid circular module dependencies, merge the v4l2-compat-ioctl32 module into videodev.

2012-03-08[media] ivtv: Fix build warningLarry Finger
In driver ivtv, there is a mismatch between the type of the radio module parameter and the storage variable, which leads to the following warning: CC [M] drivers/media/video/ivtv/ivtv-driver.o drivers/media/video/ivtv/ivtv-driver.c: In function ‘__check_radio’: drivers/media/video/ivtv/ivtv-driver.c:142: warning: return from incompatible pointer type drivers/media/video/ivtv/ivtv-driver.c: At top level: drivers/media/video/ivtv/ivtv-driver.c:142: warning: initialization from incompatible pointer type Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-03-08[media] ivtv: simplify how the decoder controls are set upHans Verkuil
The code was unnecessarily complex, introducing a hdl_out handler that was not needed. Instead just add the controls to the cxhdl.hdl handler directly. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-03-08[media] v4l2-ctrls: v4l2_ctrl_add_handler should add all refsHans Verkuil
Currently v4l2_ctrl_add_handler adds only the controls that are owned by the handler. This is wrong. Instead all controls, whether owned or not, should be added. This is also implied by the v4l2-controls.txt documentation and it is clearly the right thing to do. The only reason this was never noticed before is because we never did this. Only recent changes in ivtv made this error visible because there a third handler layer was added (handler A inherits from handler B which inherits from C, D and E). Without this change handler A only sees the controls owned by handler B and the controls from C, D and E are missing.
