2014-12-16[media] tlg2300: move to staging in preparation for removalHans Verkuil9-3935/+0
This driver hasn't been tested in a long, long time. The company that made this chip has gone bust many years ago and hardware using this chip is next to impossible to find. This driver needs to be converted to newer media frameworks but due to the lack of hardware that's going to be impossible. Since cheap alternatives are easily available, there is little point in keeping this driver alive. In other words, this driver is a prime candidate for removal. If someone is interested in working on this driver to prevent its removal, then please contact the linux-media mailinglist.

2014-07-17[media] v4l: Support extending the v4l2_pix_format structureLaurent Pinchart1-1/+0
The v4l2_pix_format structure has no reserved field. It is embedded in the v4l2_framebuffer structure which has no reserved fields either, and in the v4l2_format structure which has reserved fields that were not previously required to be zeroed out by applications. To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer structure, and use the priv field as a magic value to indicate that the application has set all v4l2_pix_format extended fields and zeroed all reserved fields following the v4l2_pix_format field in the v4l2_format structure. The availability of this API extension is reported to userspace through the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the priv field is still set to the magic value at [GS]_FMT return wouldn't be enough, as older kernels don't zero the priv field on return. To simplify the internal API towards drivers zero the extended fields and set the priv field to the magic value for applications not aware of the extensions.

2014-07-04[media] media: remove the setting of the flag V4L2_FL_USE_FH_PRIORamakrishnan Muthukrishnan1-1/+0
Since all the drivers that use `struct v4l2_fh' use the core priority checking, the setting of the flag in the drivers can be removed.

2013-07-26[media] tlg2300: fix checking firmware in poseidon_probe()Alexey Khoroshilov1-6/+4
check_firmware() makes sure firmware is in a device. It returns zero on success and error code otherwise. Also it sets down_firmware flag to 1 if downloading occurs. The only caller poseidon_probe() checks down_firmware flag and returns 0 without any initialization if it is set. That looks very strange, so the patch removes down_firmware argument of check_firmware() and returns error code if check_firmware() fails in poseidon_probe(). Not tested on real hardware.

2013-03-24[media] v4l2: pass std by value to the write-only s_std ioctlHans Verkuil1-4/+4
This ioctl is defined as IOW, so pass the argument by value instead of by reference. I could have chosen to add const instead, but this is 1) easier to handle in drivers and 2) consistent with the s_std subdev operation.
