2008-10-30V4L: struct device - replace bus_id with dev_name(), dev_set_name()Mauro Carvalho Chehab
From: Kay Sievers <kay.sievers@vrfy.org> This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.

2008-11-01v4l: remove inode argument from video_usercopyHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The inode argument was never used. Removing it from video_usercopy brings the function pointer type of video_usercopy in line with similar v4l2 functions, thus simplifying several drivers. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2008-10-19v4l: use video_device.num instead of minor in video%dHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now independent of the minor number. So instead of using the minor field of the video_device struct one has to use the num field: this always contains the kernel number of the device node. I forgot about this when I did the v4l2 core change, so this patch converts all drivers that use it in one go. Luckily the change is trivial.

2008-07-30v4l: move BKL down to the driver level.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The BKL is now moved from the video_open function in v4l2-dev.c to the various drivers. It seems about a third of the drivers already has a lock of some sort protecting the open(), another third uses video_exclusive_open (yuck!) and the last third required adding the BKL in their open function.

2008-07-21videodev: move all ioctl callbacks to a new v4l2_ioctl_ops structHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> All ioctl callbacks are now stored in a new v4l2_ioctl_ops struct. Drivers fill in a const struct v4l2_ioctl_ops and video_device just contains a const pointer to it. This ensures a clean separation between the const ops struct and the non-const video_device struct.

From: Hans Verkuil <hverkuil@xs4all.nl> The functions in a header should not belong to another module. The prio functions belong to v4l2-common.c, so move them to v4l2-common.h.

From: Mauro Carvalho Chehab <mchehab@infradead.org> struct video_device used to define a .hardware field. While initialized on severl drivers, this field is never used inside V4L.

2007-04-14usbvision: store the device database more efficientlyTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> One bit wide bitfields need to declared unsigned to have the range 0 to 1, or they have the range -1 to 0. A few techniques to reduce the driver's size by about 1700 bytes on ia32, probably more on x86-64. Put the biggest fields first, less padding is necessary that way. Put fields with a limited range into a smaller type. For example VideoChannels will fit in 3 bits, and TunerType can use 8 bits. Vin_Reg1, Vin_Reg2, and Dvi_yuv define values for 8-bit registers, but they can't just go into an 8-bit field with no changes, since -1 was used as a flag to indicate a value was not present. So what we do is create a one-bit flag for each one to indicate if a value is or is not present. This only takes 9 bits and has the added advantage that when the register isn't overridden (Vin_Reg[12] never are) it doesn't need to appear in the structure definition since the default value for the flag will be zero.
