2009-01-03V4L/DVB (10171): Use usb_set_intfdataJulia Lawall
This code had calls to both usb_set_intfdata and dev_set_drvdata, doing the same thing. The semantic patch that lead to finding this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @header@ @@ @same depends on header@ position p; @@ usb_set_intfdata@p(...) { ... } @depends on header@ position _p!=same.p; identifier _f; struct usb_interface *intf; expression data; @@ _f@_p(...) { <+... - dev_set_drvdata(&intf->dev, data); + usb_set_intfdata(intf, data); ...+> } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-01-02V4L/DVB (10135): v4l2: introduce v4l2_file_operations.Hans Verkuil
Introduce a struct v4l2_file_operations for v4l2 drivers. Remove the unnecessary inode argument. Move compat32 handling (and llseek) into the v4l2-dev core: this is now handled in the v4l2 core and no longer in the drivers themselves. Note that this changeset reverts an earlier patch that changed the return type of__video_ioctl2 from int to long. This change will be reinstated later in a much improved version.

2008-10-21V4L/DVB (9327): v4l: use video_device.num instead of minor in video%dHans Verkuil
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.

2008-10-12V4L/DVB (9116): USB: remove info() macro from usb media driversGreg Kroah-Hartman
USB should not be having it's own printk macros, so remove info() and use the system-wide standard of dev_info() wherever possible.

2008-10-12V4L/DVB (8613): v4l: move BKL down to the driver level.Hans Verkuil
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.

2008-07-27V4L/DVB (8523): v4l2-dev: remove unused type and type2 field from video_deviceHans Verkuil
The type and type2 fields were unused and so could be removed. Instead add a vfl_type field that contains the type of the video device. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-07-26V4L/DVB (8482): videodev: move all ioctl callbacks to a new v4l2_ioctl_ops ↵Hans Verkuil
struct 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.

2008-07-23V4L/DVB (8430): videodev: move some functions from v4l2-dev.h to ↵Hans Verkuil
v4l2-common.h or v4l2-ioctl.h 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. The ioctl functions belong to v4l2-ioctl.c, so create a new v4l2-ioctl.h header and move those functions to it.

2007-07-18V4L/DVB (5678): Zr364xx: fix return valuesAkinobu Mita
This patch fixes several return value related problems in zr364xx. - return -ENOMEM instead of -ENODEV on out of memory - zr364xx checks video_register_device() error only when its return value is -1. But video_register_device() doesn't always return -1 on error. - If usb_register() returns error, module_init() wrongly returns 1: retval = usb_register(&zr364xx_driver) < 0; ... return retval; And it allows the module to be loaded. Because sys_init_module() doesn't see positive return value as error.
