2006-12-01Improve debug msgs to show fourcc and buffer length on video_ioctl2Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-11-20Remove the need of a STD array for drivers using video_ioctl2Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> CC: Jonathan Corbet <corbet@lwn.net> 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. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2006-10-13Fix oops in VIDIOC_G_PARMMauro Carvalho Chehab
From: Jonathan Corbet <corbet-v4l@lwn.net> 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>
2006-10-09Fixed an if-block to avoid floating with debug-messagesMauro Carvalho Chehab
From: Enrico Scholz <enrico.scholz@informatik.tu-chemnitz.de> 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. Signed-off-by: Enrico Scholz <enrico.scholz@informatik.tu-chemnitz.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-09-14Add a default method for VIDIOC_G_PARMMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> 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>
2006-09-13Fix VIDIOC_ENUMSTD ioctl in videodev.cMauro Carvalho Chehab
From: Sascha Hauer <s.hauer@pengutronix.de> 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>
2006-09-11Copy-paste bug in videodev.cMauro Carvalho Chehab
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>

2006-07-25videodev: Check return value of class_device_register() correctlyTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Errors are return values < 0, not != 0. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2006-07-25videodev: Handle class_device related errorsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> 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. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2006-07-23Fix for compilation without V4L1 or V4L1_COMPATMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> 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>
