2012-03-20[media] au8522: bug-fix: enable modulation AFTER tune (instead of before tuning)Michael Krufky1-5/+5
The au8522 driver programs the tuner after programming the demodulator, but the tuner should be programmed first. This patch fixes this behavior. EDIT: Apparantly Devin created a similar patch some time ago, but hasn't submitted it for merge. I never saw his patch, but I thank him anyhow for his efforts. In addition, Devin pointed out a flaw in my patch: This newly generated patch takes Devin's comments into account.

2012-03-20[media] media: Initialize the media core with subsys_initcall()Laurent Pinchart1-1/+1
Media-related drivers living outside drivers/media/ (such as the UVC gadget driver in drivers/usb/gadget/) rely on the media core being initialized before they're probed. As drivers/usb/ is linked before drivers/media/, this is currently not the case and will lead to crashes if the drivers are not compiled as modules. Register media_devnode_init() as a subsys_initcall() instead of module_init() to fix this.

2012-03-20[media] V4L/v4l2-dev: Make 'videodev_init' as a subsys initcallBhupesh Sharma1-1/+1
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. Kernel Crash Dump: ------------------ designware_udc designware_udc: Device Synopsys UDC probed csr 90810000: plug 90812000 g_webcam gadget: uvc_function_bind Unable to handle kernel NULL pointer

2012-03-19[media] media, cx231xx: Fix double free on closeJesper Juhl2-5/+2
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.

Remove delays added for STV0288 frontend. This patch significantly speeds up channel change and scan. It requires patch 10161-STV0288 increase delay between carrier search. Signed-off-by: Malcolm Priestley <tvboxspy@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-03-19[media] STV0288 increase delay between carrier searchMalcolm Priestley1-1/+1
The current delay of 30uS is too short to recover any carrier. In the lmedm04 driver delays were added to overcome carrier lock problems. The typical delay was 30mS (2 x 15ms register write 0x2c and read 0x24). Other drivers that use STV0288 don't appear to have any delay are likely to have also suffered this problem.

2012-03-19[media] v4l: Add custom compat_ioctl32 operationLaurent Pinchart2-13/+14
Drivers implementing custom ioctls need to handle 32-bit/64-bit compatibility themselves. Provide them with a way to do so. To avoid circular module dependencies, merge the v4l2-compat-ioctl32 module into videodev. There is no point in keeping them separate, as the v4l2_compat_ioctl32() function is required by videodev if CONFIG_COMPAT is set anyway.

The tea575x-tuner module has been updated to use the latest V4L2 framework functionality. This also required changes in the drivers that rely on it. The tea575x changes are: - The drivers must provide a v4l2_device struct to the tea module. - The radio_nr module parameter must be part of the actual radio driver, and not of the tea module. - Changed the frequency range to the normal 76-108 MHz range instead of 50-150. - Add hardware frequency seek support. - Fix broken rxsubchans/audmode handling. - The application can now select between stereo and mono. - Support polling for control events. - Add V4L2 priority handling. And radio-sf16fmr2.c now uses the isa bus kernel framework.
