* V4L/DVB (4901): Improve debug msgs to show fourcc and buffer length on ↵Mauro Carvalho Chehab2006-12-10

* V4L/DVB (4861): Remove the need of a STD array for drivers using video_ioctl2Mauro Carvalho Chehab2006-12-10
| | | | | | | | | | | video_ioctl2 will auto-generate standard entries at ENUM_FMT. Also, now, a driver may return a subset of the video array at the return, to be stored as the current_norm. For example, a driver may ask for V4L2_STD_PAL. At return, driver may change it to V4L2_STD_PAL_B. This way, a futher call to G_STD will return the exact detected video std.

* V4L/DVB (4743): Fix oops in VIDIOC_G_PARMJonathan Corbet2006-10-13
| | | | | | | | | | The call to v4l2_std_construct() in the VIDIOC_G_PARM handler treats vfd->current_norm as if it were an index - but it's not. The result is an oops if the driver has no vidioc_g_parm() method defined. Here's the fix. Signed-off-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (4740): Fixed an if-block to avoid floating with debug-messagesEnrico Scholz2006-10-13
| | | | | | | | | | The dbgarg() macro in videodev.c contains some printk() statements where only the first one is influenced by an if-statement. This causes floating with debug-messages which is fixed by this patch by adding a '{ ... }' pair.

* V4L/DVB (4637): Add a default method for VIDIOC_G_PARMMauro Carvalho Chehab2006-09-26
| | | | | | | | For most drivers, VIDIOC_G_PARM will just return the current standard fps. So, instead of failing, drivers based on video_ioctl2 will implement the default method. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

* V4L/DVB (4622): Copy-paste bug in videodev.cSascha Hauer2006-09-26

* [PATCH] VIDIOC_ENUMSTD bugJonathan Corbet2006-09-25
| | | | | | | | | | | | | | | | | | | | | | | The v4l2 API documentation for VIDIOC_ENUMSTD says: To enumerate all standards applications shall begin at index zero, incrementing by one until the driver returns EINVAL. The actual code, however, tests the index this way: if (index<=0 || index >= vfd->tvnormsize) { ret=-EINVAL; So any application which passes in index=0 gets EINVAL right off the bat - and, in fact, this is what happens to mplayer. So I think the following patch is called for, and maybe even appropriate for a 2.6.18.x stable release.

* V4L/DVB (4368): Bttv: use class_device_create_file and handle errorsTrent Piepho2006-07-29
| | | | | | | | | | | Revert bttv-driver.c from video_device_create_file() to use class_device_create_file() again. video_device_create_file() is only available when V4L1 is on. Proper error checking is added for failure of class_device_create_file(). Will print error message and unroll partially created sysfs entries.

* V4L/DVB (4367): Videodev: Handle class_device related errorsTrent Piepho2006-07-29
| | | | | | | | | | | | | | | | Add proper error checking and roll-back for failure of class_device_create_file() in videodev.c. Print error messages and unroll partially created sysfs entries. Also, failure of class_device_register() in video_register_device() is handled correctly. It was failing to de-allocate the minor number. This must be done in video_register_device(), since the caller has no way of knowing if failure occurred before or after the class device was registered. Also added an error message if video_register_device() is called with an unknown type, which should never happen.

* V4L/DVB (4316): Check __must_check warningsMichael Krufky2006-07-29
| | | | | | | | | | | | | | | | | | | | Check __must_check warnings for class_device_register and class_device_create_file video_device_create_file was declared as a void, but instead should return the int value of class_device_create_file. Move the check from bttv-driver.c into v4l2-dev.h, because all other callers of video_device_create_file must also be checked. Replace the call to class_device_create_file in videodev.c with video_device_create_file, as defined in v4l2-dev.h, so that the return value of class_device_create_file will be checked. Check the return value of class_device_register in videodev.c and pvrusb2-sysfs.c Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
