2006-09-26V4L/DVB (4637): Add a default method for VIDIOC_G_PARMMauro Carvalho Chehab1-3/+23
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>
2006-09-26V4L/DVB (4628): Fix VIDIOC_ENUMSTD ioctl in videodev.cSascha Hauer1-1/+1
Do not return -EINVAL for index=0 in VIDIOC_ENUMSTD, because it is a valid index Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-09-26V4L/DVB (4622): Copy-paste bug in videodev.cSascha Hauer1-2/+2
This patch fixes a copy-paste bug in videodev.c where the vidioc_qbuf() function gets called for the dqbuf ioctl. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-09-26[PATCH] VIDIOC_ENUMSTD bugJonathan Corbet1-1/+1
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.

2006-07-30V4L/DVB (4379): Videodev: Check return value of class_device_register() ↵Trent Piepho1-1/+1
correctly Errors are return values < 0, not != 0. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-07-30V4L/DVB (4368): Bttv: use class_device_create_file and handle errorsTrent Piepho1-3/+4
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.

2006-07-30V4L/DVB (4367): Videodev: Handle class_device related errorsTrent Piepho1-0/+11
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.

2006-07-30V4L/DVB (4343): Fix for compilation without V4L1 or V4L1_COMPATMauro Carvalho Chehab1-2/+6
Removed usage of HAVE_V4L1 Including videodev.h will just include videodev2.h if V4L1 is not supported V4L1 code at core drivers will honor CONFIG_V4L1_COMPAT stuff Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-07-30V4L/DVB (4316): Check __must_check warningsMichael Krufky1-3/+8
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>

2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+436
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!
